How to align the text to start? Ive wrap it with child column but it didnt work.
atm i think that flutter is more complicated than native when we are trying to positioning the layout, but when we are making a dynamic or interactive layout its better.

Try below code hope its helpful to you. add crossAxisAlignment: CrossAxisAlignment.start, to first column
Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Row(
children: [
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: [
Text(
"Name",
),
SizedBox(
height: 8,
),
],
),
),
Container(
width: 18,
height: 18,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: DecorationImage(
image: AssetImage('assets/tripple_dot.png')),
),
)
],
),
Text(
"Rp. 10.000",
),
],
),
Your result screen->

Add
crossAxisAlignment: CrossAxisAlignment.start,
to first column, it should work in some case if it didn't work. You can try text alight property from Text widget..

Flutter Align the widget onto the top in ROW

I have an issue in ROW that one child has many items so it is large and another child has fewer items so its height is small so the less item is showing in the center of the ROW, so I need it to align to the top inside the ROW, you can have a look at the image.
Please have a look at my code as well.
rowList = Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: mainBodyList,
);
MAIN BODY LIST
Container(
width: screenWidth * 0.49,
child: Card(
color: Colors.white,
child: Column(
children: <Widget>[
Container(
//width: 200,
padding: EdgeInsets.symmetric(vertical: 8, horizontal: 8),
decoration: BoxDecoration(
color: Colors.black12,
),
child: Row(
children: <Widget>[
ClipOval(
child: Material(
color: Colors.white,
child: SizedBox(
width: 40,
height: 40,
child:
/*Image.asset(
'assets/icons/doc_icon.png'),*/
Icon(
Icons.playlist_add_check,
color: AppTheme.primaryColor,
),
),
),
),
Flexible(
child: Padding(
padding: const EdgeInsets.all(8.0),
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
Text(
_localization.localeString(name),
style: TextStyle(color: AppTheme.primaryColor),
),
],
),
),
),
],
),
),
Container(
child: Column(
children: _dynamicListWidget(list),
),
),
],
),
),
);

You need to set crossAxisAlignment as CrossAxisAlignment.start
Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
crossAxisAlignment: CrossAxisAlignment.start,
children: mainBodyList,
);

Custom toolbar with background shape and back button

I'm making custom toolbar with background shape but my back button is getting correct the alignment to the text
Widget _toolBar(String headerText){
return Container(
decoration: BoxDecoration(
color: MyColors.greenHeader,
borderRadius: new BorderRadius.only(
bottomLeft: const Radius.circular(15.0),
bottomRight: const Radius.circular(15.0))
),
child:Center(child: Stack(
children: <Widget>[
Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 1,
child:Text(headerText,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
)
),),
],),
Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Flexible(
flex: 1,
child:IconButton(
icon: new Icon(Icons.arrow_back_ios),
color: Colors.white,
onPressed: (){},
)
),
],),
],
),)
);
}
The above code also tried without stack by Using Row with expanded but the text alignment going wrong the text getting center to its expanded widget n
return Scaffold(
body: Stack(
children: <Widget>[
Container(
decoration: _buildBackground(),
),
Column(
crossAxisAlignment: CrossAxisAlignment.stretch,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 13,
child:_toolBar('VENUE LOGIN')
),
Expanded(
flex: 87,
child: Container(
child: LoginBody(),
),
)
],
)
],
),
);

You can try center your Text and IconButton widgets.
Stack(
children: <Widget>[
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Expanded(
flex: 1,
child: Text(headerText,
textAlign: TextAlign.center,
style: TextStyle(
color: Colors.white,
fontSize: 18.0,
)),
),
],
),
),
Center(
child: Row(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Flexible(
flex: 1,
child: IconButton(
icon: new Icon(Icons.arrow_back_ios),
color: Colors.white,
onPressed: () {},
)),
],
),
),
],
),

You can Try like this
appBar: PreferredSize(
preferredSize: Size(null, 100),
child: Container(
width: MediaQuery.of(context).size.width,
height: 100,
child: ClipRRect(
borderRadius: BorderRadius.only(
bottomLeft: Radius.circular(15),
bottomRight: Radius.circular(15)
),
child: Container(
color: Colors.green,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Icon(Icons.navigate_before,size: 40,),
Text("Center",style: TextStyle(fontSize: 30),),
Icon(Icons.navigate_before,color: Colors.transparent,),
],
),
),
),
),
),

Flutter | How to make custom button of BottomNavigationBar in flutter?

I want make a button with text and icon inside it, with custom background color and custom width. with fix position (not scrollable). would you like to help me please ?
here are the code:
bottomNavigationBar: BottomNavigationBar(
type: BottomNavigationBarType.shifting,
currentIndex: 0, // this will be set when a new tab is tapped
items: [
BottomNavigationBarItem(icon: Icon(Icons.supervised_user_circle), title: Text('Players'),backgroundColor: Colors.red),
BottomNavigationBarItem(icon: Icon(Icons.whatshot), title: Text('Trending'),backgroundColor: Colors.blueAccent),
BottomNavigationBarItem(icon: Icon(Icons.access_time), title: Text('Highlights'),backgroundColor: Colors.yellow)
]
its only give a color for the icon.
this is what I want:

Here you go
Widget build(context) {
return Scaffold(
bottomNavigationBar: Container(
height: 56,
margin: EdgeInsets.symmetric(vertical: 24, horizontal: 12),
child: Row(
children: <Widget>[
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.chat, color: Colors.white), Text("CHAT", style: TextStyle(color: Colors.white))],
),
),
Container(
width: 66,
color: Colors.green,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[Icon(Icons.notifications_active, color: Colors.white), Text("NOTIF", style: TextStyle(color: Colors.white))],
),
),
Expanded(
child: Container(
alignment: Alignment.center,
color: Colors.red,
child: Text("BUY NOW", style: TextStyle(fontWeight: FontWeight.bold, fontSize: 18)),
),
),
],
),
),
);
}

You may want to look at the concept of a BottomAppBar instead.
This bar accepts any widget as children not just BottomNavigationBarItems.
You could try this:
BottomAppBar(
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
Expanded(
child: SizedBox(
height: 44,
child: Material(
type: MaterialType.transparency,
child: InkWell(
onTap: () {},
child: Column(
mainAxisSize: MainAxisSize.min,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
Icon(Icons.add, color: Colors.blue, size: 24),
Text("Add")
],
),
),
),
),
),
]
),
)
