I want to make the login button visible only when user enter the credentials in Text Form Field (Email and Password), otherwise login button should be invisible.
My LoginPage is designed as below:-
class _LoginPageState extends State<LoginPage> {
final _formKey = GlobalKey<FormState>();
late String _email, _password, error = '';
bool _obscureText = true;
bool _isKeyboardVisible = true;
bool _canShowButton = true;
final AuthenticationService _authenticationService = AuthenticationService();
_hideWidget(){
setState(() {
_canShowButton = !_canShowButton;
});
}
_toggle() {
setState(() {
_obscureText = !_obscureText;
});
}
_submit() async {
if(_formKey.currentState!.validate()){
_formKey.currentState?.save();
dynamic result = await _authenticationService.loginWithEmail(email: _email, password: _password);
if(result == null) {
setState(() => error = 'Es wurde kein Benutzerkonto gefunden. Bitte erstellen Sie zuerst das Konto');
} else {
Navigator.pushNamed(context, HomePage.id);
}
print(_email);
print(_password);
}
}

In short I have added the bool variable and function as below. After that in onPressed of login Button I called _hideWidget().
bool _canShowButton = true;
_hideWidget(){
setState(() {
_canShowButton = !_canShowButton;
});
Padding(
padding: const EdgeInsets.only(top: 10),
child: Container(
width: MediaQuery.of(context).size.width - 70,
height: MediaQuery.of(context).size.height * 0.09,
child: !_canShowButton ? SizedBox.shrink() : TextButton(
style: TextButton.styleFrom(
primary: Colors.white,
backgroundColor: color,
elevation: 5,
shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(10.0))
),
onPressed: () {
_hideWidget();
},
child: Text('Anmelden')),
),
),
What I have achieved is: The Login Button is there on the page and when I click on TextFormField it gets disappear.
Want to achieve: Login Button should be invisible on the screen and when user enters the credentials after that it should appear.
Is there any way to achieve this??
This is how you can tell if there's data in the textfield or not, if there is it'll change isFilled to true.
bool isFilled = false;
TextFormField(
onChanged: (val) {
setState(() {
(val.isEmpty) ? isFilled = false : isFilled = true;
});
},
)
Now to show the button when there's data in the textfield you can use ternary operator.
(isFilled)?TextButton(onPressed: (){}, child: Container()) : Container()
Just switch TextButton with your button. Ternary operators work like so
(condition) ? (do if true) : (do if false)
in this case, you're showing the button if isFilled = true, and an empty container if not
Well the simplest way of implementing this is to add a TextEdittingController to each Textfield and then render the button only when the TextEdittingController.tex is not empty,when it's empty you can render an empty container otherwise render the button,use a simple tenary operator to do this
I have two widgets which I shared codes below, In first card widget for user selecting ingredients, second card will be used for displaying selected ingrediens, initial both screen will be empty, when user add an igredients both widget will be rebuilt by according to selected ingredients, I could handle it displaying in first widget, but I can not handle to display selectedIngredient list data when it changes, I know I have to use provider packages but I could not implement for my code, I have stuck please help me.. .

Make a provider class that mixin with ChangeNotifier.
Wrap your widget prior calling the provider class with MultiProvider widget. Likewise:
MultiProvider (
providers: [
ChangeNotifierProvider.value(value: IngredientsProvider()),
],
child: YourWidget(), //You can wrap your MaterialApp here
)
Create your needed methods that changes the selected data and call notifyListeners() inside your method. It will rebuild your desired widget where you listen to them.
Example:
class IngredientsProvider with ChangeNotifier {
List<String> _selectedIngredients = [];
List<String> get selectedIngredients() {
return _selectedIngredients;
}
void addIngredient(String ingredient) {
_selectedIngredients.add(ingredient);
notifyListeners();
}
}
In your widget listen to them:
Widget1 {
//Call this in you onPress/onTap
void addIngredient(String ing, BuildContext ctx) {
Provider.of<IngredientsProvider>(ctx, listen:
false).addIngredient(ing);
}
........
#override
Widget build(BuildContext context) {
//Use this list to select
List<String> _ingredients = Provider.of<IngredientsProvider>(context, listen:
true).ingredients;
}
........
}
Use in the 2nd Widget in this way.
Widget2 {
........
#override
Widget build(BuildContext context) {
//Use this list to show
List<String> _ingredients = Provider.of<IngredientsProvider>(context, listen:
true).ingredients;
}
........
}
I am currently working on the ui stuff for the appliction, so the thing is i have one gesture as a parent that swipes up and down and based on it the position of the widgets gets changed but the problem is the child gesture does not get any precedence when tapped on it it gives the precedence. So my tree structure is Pageview.builder which has single widget with topmost parent as Gesturedetector and the children accrodingly, Can any one tell me what i am doing wrong or any improvements to get the gesture for each.
Below is the sample code that i have been working on:

You can add Color to the last AnimatedPositioned which use text widget.item.locationName in your code, like:
AnimatedPositioned(
curve: Curves.ease,
duration: Duration(milliseconds: 400),
bottom: moveWidget
? 10
: MediaQuery.of(context).size.height * 0.20,
left: 10.0,
right: 0.0,
top: moveWidget
? 15
: MediaQuery.of(context).size.height * 0.70,
child: Container(
color: Colors.white,
Text(
'${widget.item.locationName}',
style: TextStyle(fontSize: 30, color: Colors.white),
),
),
),
You will see a white screen (the widget which blocking you) when you scroll up. You can fix it by 2 ways
Change the bottom 10 to a larger number
Move this part of AnimatedPositioned to Top of the Stack widget
The Nested Gesture should work probably as you expected.
First of All you are using multiple Scaffold in a single page which is not recommended.
And remove the unwanted widgets from your tree which will help you to debug a way more better level. And Next you can try with passing a Callback function from parent to child which can eventually solve your problem
i have a Flutter app which should show a counting down timer in an alert box for Phone code confirming (i need this timer to resend the code to my user when 60 second is up) , i start timer when i click on Confirm Button , but the problem is that the timer is not showing that he's going down he stills with a fixed value.
here is my alert box
Alert Box with timer NOT SHOWING COUNT DOWN
here is my timer Function :
int _counter = 60;
Timer _timer;
void _startTimer(){
_counter = 60;
if(_timer != null){
_timer.cancel();
}
_timer = Timer.periodic(Duration(seconds: 1), (timer){
setState(() {
(_counter > 0) ? _counter-- : _timer.cancel();
});
});
}
here is my alert Box code :
void alertD(BuildContext ctx) {
var alert = AlertDialog(
// title: Center(child:Text('Enter Code')),
shape: RoundedRectangleBorder(
borderRadius: BorderRadius.all(Radius.circular(20.0))),
backgroundColor: Colors.grey[100],

),
));
showDialog(
context: ctx,
builder: (BuildContext c) {
return alert;
});
}
that's how i'm calling my alert dialog and my timer when i click Confirm Button :
onTap: () {
_startTimer;
alertD(context);
},
You can copy paste run full code below
You can use StreamBuilder and StreamController
AlertDialog content continually receive stream int from Timer
code snippet
StreamController<int> _events;
#override
initState() {
super.initState();
_events = new StreamController<int>();
_events.add(60);
}
...
_timer = Timer.periodic(Duration(seconds: 1), (timer) {
(_counter > 0) ? _counter-- : _timer.cancel();
print(_counter);
_events.add(_counter);
});
...
content: StreamBuilder<int>(
stream: _events.stream,
builder: (BuildContext context, AsyncSnapshot<int> snapshot) {
...
Text('00:${snapshot.data.toString()}'),

I made a list in my stateful widget class that is going to be filled with some values when the user selects cards, I have a showDialog function on a button in my app that every time it is clicked a form will be shown to the user.
the problem is after the user come back from the form by clicking on the Ok button the stateful class will be recreated and clean up all my list's values (the ActivityPeopleCard class called again)... how to keep the value of the list even after coming back from showDialog form?

after the user come back from the form the _cost list will be initialized again with null and shows null values instead of previous values
Create a variable in your initial state that returns your Container. Then in your build method return your variable. This will stop the list refreshing/resetting every time the build method is called
