save a temp file to download file Android/IOS in flutter

I have a question, I am using Path-provider to generate a path for a new generated PDF file from my App… but path provider is storing the file in the App folder & after closing the app the file will be deleted, I am using getExternalStorageDirectory… how can I save that file to downloads when selected.
Anybody can help me?
just small explanation... the PDF file will be viewed from the App using
flutter_full_pdf_viewer
then from that page I need to let the user select if he wants to save the file or close the hall file.
This is the code for the file save
try {
final dir = await getExternalStorageDirectory();
String documentPath = dir.path;
fullPath = "$documentPath/$fileName";
final file = File('$fullPath');
await file.writeAsBytes(await pdf.save());
print('XXXXXXXXX$fileName');
return file;
} catch (e) {
// print('we have a problem');
}
print(fullPath);
}
And this is the PDFViewer page code
Widget build(BuildContext context) {
return Scaffold(
body: Container(
child: PDFViewerScaffold(
appBar: AppBar(
title: Text('PDF page'),
actions: <Widget>[
IconButton(
icon: Icon(Icons.share),
onPressed: () {
Share.shareFiles(
['$path'],
);
print('iiiiiiiiiiiiii$path');
},
),
IconButton(
icon: Icon(Icons.save),
onPressed: () {},
),
],
),
path: path,
),
),
);
}
}
============================================================================
after I modified the code now it looks like this for the PDF_save Page (for Methods)
Future<bool> saveFolder(String fileName) async {
Directory directory;
try {
if (Platform.isAndroid) {
if (await _requestPermission(Permission.storage)) {
directory = await getExternalStorageDirectory();
String newPath = "";
print('ZZZZZZZZzzzzZZZZz$directory');
List<String> paths = directory.path.split("/");
for (int x = 1; x < paths.length; x++) {
String folder = paths[x];
if (folder != "Android") {
newPath += "/" + folder;
} else {
break;
}
}
newPath = newPath + "/SAMApp";
directory = Directory(newPath);
print('AAAAAAAAAAAAAAAA$newPath');
print('AAAAAAAAAAAAAAAA$fileName');
} else {
return false;
}
} else {
if (await _requestPermission(Permission.photos)) {
directory = await getTemporaryDirectory();
} else {
return false;
}
}
File saveFile = File(directory.path + "/$fileName");
if (!await directory.exists()) {
await directory.create(recursive: true);
}
if (await directory.exists()) {
// await dio.download(saveFile.path, onReceiveProgress: (value1, value2) {
// setState(() {
// progress = value1 / value2;
// });
// });
// if (Platform.isIOS) {
// await ImageGallerySaver.saveFile(saveFile.path,
// isReturnPathOfIOS: true);
// }
File savedFile = File(directory.path + "/$fileName");
var savedPath = directory.path + "/$fileName";
print('$savedPath');
print('$savedFile');
savedFile.writeAsBytesSync(byteList);
if (savedPath != null) {
print('NO saved Path');
// await Navigator.pushReplacement(
// context,
// MaterialPageRoute(
// builder: (context) => SharePage(
// imageFilebytes: pngBytes,
// imagePath: savedPath,
// )),
// );
} else {
print("waiting for savedpath");
}
return true;
}
return false;
} catch (e) {
print(e);
return false;
}
}
did I made something wrong??

This is worked to save the image. It can be useful for you.
Future<bool> saveFile(var byteList, BuildContext context) async {
Directory storageDir;
try {
if (await requestPermission(Permission.storage)) {
storageDir = await getExternalStorageDirectory();
String newPath = '';
List<String> folders = storageDir.path.split('/');
for (int x = 1; x < folders.length; x++) {
String folder = folders[x];
if (folder != 'Android') {
newPath += '/' + folder;
} else {
break;
}
}
newPath = newPath + '/xyz';
storageDir = Directory(newPath);
} else {
if (await requestPermission(Permission.photos)) {
storageDir = await getTemporaryDirectory();
} else {
return false;
}
}
if (!await storageDir.exists()) {
await storageDir.create(recursive: true);
}
if (await storageDir.exists()) {
//List<int> bytesSync = widget.pickedImage.readAsBytesSync();
DateTime date = DateTime.now();
String baseFileName = 'abc' + date.toString() + ".jpg";
File savedFile = File(storageDir.path + "/$baseFileName");
savedPath = storageDir.path + "/$baseFileName";
savedFile.writeAsBytesSync(byteList);
if (savedPath != null) {
await Navigator.pushReplacement(
context,
MaterialPageRoute(
builder: (context) => SharePage(
imageFilebytes: pngBytes,
imagePath: savedPath,
)));
} else {
print("waiting for savedpath");
}
return true;
}
} catch (e) {
print(e);
}
return false;

Exchange rate currency format setting in Flutter

I have an exchange rate application in flutter, but I want to make the currency format the same as below, how can I do it?
My Code :
import 'package:flutter/services.dart';
import 'package:intl/intl.dart';
import '../Utils.dart';
class CurrencyInputFormatter extends TextInputFormatter {
TextEditingValue formatEditUpdate(
TextEditingValue oldValue, TextEditingValue newValue) {
if (newValue.selection.baseOffset == 0) {
print(true);
return newValue;
}
double value = double.parse(newValue.text);
final formatter = NumberFormat("#,##0", "tr-TR");
String newText = formatter.format(value);
print(newText);
return newValue.copyWith(
text: newText,
selection: new TextSelection.collapsed(offset: newText.length));
}
}
I want to do

Intl actually provides you a way to do so.
import 'package:intl/intl.dart';
final moneyText = 1000;
NumberFormat.simpleCurrency().format(moneyText);
If you are already using translation, you should have intl already.

You can achieve this with flutter_masked_text package it can do exactly the same.

I solved. works great.
library currency_text_input_formatter;
import 'dart:math';
import 'package:flutter/services.dart';
import 'package:intl/intl.dart';
/// The `symbol` argument is used to symbol of NumberFormat.
/// Put '\$' for symbol
///
/// The `locale` argument is used to locale of NumberFormat.
/// Put 'en' or 'es' for locale
///
/// The `decimalDigits` argument is used to decimalDigits of NumberFormat.
/// Defaults `decimalDigits` is 2.
class CurrencyTextInputFormatter extends TextInputFormatter {
#override
TextEditingValue formatEditUpdate(
TextEditingValue oldValue, TextEditingValue newValue) {
if (newValue.text.isEmpty) {
return newValue.copyWith(text: '');
} else if (newValue.text == ".") {
return newValue.copyWith(
text: '0.00',
selection: TextSelection.collapsed(offset: 2),
);
} else {
NumberFormat f = NumberFormat("#,###,###.00", "en_US");
double newNumber = 0;
if ((!newValue.text.contains(".")) && oldValue.text.contains('.')) {
String tempString = newValue.text.replaceAll(f.symbols.GROUP_SEP, '');
tempString = tempString.substring(0, tempString.length - 2) +
"." +
tempString.substring(tempString.length - 2);
newNumber = double.parse(tempString);
} else {
newNumber = double.parse(newValue.text
.replaceAll(f.symbols.GROUP_SEP, '')
.replaceAll("..", '.'));
}
String newString = f.format(newNumber);
int cursorPosition = 0;
if (oldValue.text.length > newString.length) {
cursorPosition = -1;
} else if (oldValue.text.length < newString.length) {
cursorPosition = 1;
} else {
if (oldValue.text.replaceAll(f.symbols.GROUP_SEP, '').length >
newValue.text.replaceAll(f.symbols.GROUP_SEP, '').length) {
cursorPosition = -1;
if (newString == "0.00" && oldValue.selection.baseOffset == 0) {
newString = "";
}
} else if (oldValue.text.replaceAll(f.symbols.GROUP_SEP, '').length <
newValue.text.replaceAll(f.symbols.GROUP_SEP, '').length) {
cursorPosition = 1;
} else if (oldValue.selection.extentOffset >
oldValue.selection.baseOffset) {
cursorPosition =
oldValue.selection.baseOffset - oldValue.selection.extentOffset;
newString =
newString.substring(0, oldValue.selection.baseOffset - 1) +
newString.substring(oldValue.selection.baseOffset + 1);
newNumber = double.parse(newString
.replaceAll(f.symbols.GROUP_SEP, '')
.replaceAll("..", '.'));
newString = f.format(newNumber);
if (newString == "0.00" && oldValue.selection.baseOffset == 0) {
newString = "";
}
}
}
return TextEditingValue(
text: newString,
selection: TextSelection.collapsed(
offset: oldValue.selection.extent.offset +
cursorPosition +
(f.symbols.GROUP_SEP.allMatches(newString).length -
f.symbols.GROUP_SEP.allMatches(oldValue.text).length)),
);
}
}
}

How do you print/output returned Raw text from a React Module function(Get Call Log)?

I'm creating a react native android application to access and print out an android phone/tablet's call logs in a sectionlist for the day/date (eg. Yesterday; 26/07/17; 25/07/17 etc);but I am stuck at the actual printing out of the string of call logs in the react class - when invoking the method from the module. Apparently react methods can only "return" void.
I tried to use promises but got stuck with async and await. I can't use npm 5(node which has async and await) because I created a project using "react native init" for the physical device testing; and npm is not supported/stable(shown on terminal). I used "sudo npm install -g npm#latest-4" so I could use init .
I tried installing async and await manually using "npm install async --save" and "npm install asyncawait". When I ran later it made no difference.
I really just want to output the call details as a sectionlist on the screen of my physical android device.
I've tried google; but maybe my keywords were not good enough; so I got little help. It would also be nice if you could give me an indication of whether a .xml file is needed and if so; how it would look. I've posted my code for the java native module method and the Class where I import the module from a helper .js class. I apologise for the commented code; I tried many methods to print.
The latest error I was getting; when I could actually toast the ' tag' was "undefined is not an object (evaluating 'n.data.length')". This after resolving "expected a component class got object" and "undefined is not a function".

I figured it out. I was mixing up promises and callback code.
I used promises again and it worked.
const log = CallLogAndroid.getCallDetails().then(function(value) {
console.log(value);
".then(function(..." is used to resolve a call back. It was not supposed to be added and an async function had to be used. With promises; just calling the function should return the data.

Ionic app does not work properly on android device

I am new to ionic 1. I have been making an app where I have used SQLite. The app runs perfectly on browser but works partially on device. There is a button that does not work. The code that contains this button is given below. The button function name is charge. Here's my code:
angular.module('app.cartCtrl', ['ngCordova'])
.controller('cartCtrl', ['$scope', '$stateParams', '$state', '$cordovaSQLite', '$ionicHistory', '$ionicPopup',// The following is the constructor function for this page's controller. See https://docs.angularjs.org/guide/controller
$stateParams.parameterName
function ($scope, $stateParams, $state, $cordovaSQLite, $ionicHistory, $ionicPopup) {
$scope.items = [];
$scope.grandTotal = 0;
$scope.receiptnumber = 0;
$scope.receiptnumber = $scope.receiptnumber + 1;
$scope.items = [];
$scope.item = {};
$scope.grandTotal = null;
var query2 = "SELECT * FROM items WHERE quantity!='' ";
console.log(query2);
$cordovaSQLite.execute(db, query2, []).then(function (res) {
if (res.rows.length > 0) {
for (var i = 0; i < res.rows.length; i++) {
$scope.items.push({
itemname: res.rows.item(i).itemname,
price: res.rows.item(i).price,
quantity: res.rows.item(i).quantity,
});
$scope.items = $scope.items;
}
} else {
console.log("No results found");
}
}, function (err) {
console.error("error=>" + err);
});
$ionicHistory.clearCache();
$ionicHistory.clearHistory();
var query = "SELECT SUM(total) FROM items";
$cordovaSQLite.execute(db, query, []).then(function (res) {
$scope.grandTotal = res.rows[0]['SUM(total)'];
//$scope.grandtotal = parseFloat(res.rows[0]['SUM(total)']);
// console.log("Grand total is" + res.rows[0]['SUM(total)']);
}, function (err) {
console.error("error=>" + err);
});
$scope.myGoBack = function () {
$state.go("menu.sales");
};
$scope.charge = function () {
$state.go('transactionsuccess');
}
}])
I am in doubt with below piece of code. Will it work on device or emulator:
res.rows[0]['SUM(total)']

Try with this updated query and check the post the log what ur getting
var query2 = "SELECT * FROM items WHERE quantity!='' ";
console.log(query2);
$cordovaSQLite.execute(db, query2, [5]).then(function (res) {
if (res.rows.length > 0) {
for (var i = 0; i < res.rows.length; i++) {
$scope.items.push({
itemname: res.rows.item(i).itemname,
price: res.rows.item(i).price,
quantity: res.rows.item(i).quantity,
});
$scope.items = $scope.items;
}
} else {
console.log("No results found");
}
}, function (err) {
console.error("error=>" + err);
