Whenever I try to set up a CupertinoPicker
in a ModalBottomSheet
in a Column
, Row
, or in a Container
it seems to occupy the maximum possible place.
Is there anyway to limit the size/heigt of the ModalBottomSheet
to the actual size of the CupertinoPicker
, which is obviously much smaller in height than the ModalBottomSheet
(as becomes apparent through its grey background color).
Here is my code:
import 'package:flutter/material.dart';
import 'package:flutter/cupertino.dart';
void main() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(body:
Center(child: RaisedButton(onPressed: () => showPicker(context),
child: Text('Show Bottom Sheet')),)
);
}
Widget showPicker(BuildContext context) {
showModalBottomSheet(
context: context,
builder: (context) {
return Container(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('This is a picker'),
Expanded(
child: Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Expanded(
child: Container(
height: 100,
child: CupertinoPicker(
itemExtent: 30,
onSelectedItemChanged: (int index) {
print(index);
},
children: <Widget>[
Center(child: Text("Item 1")),
Center(child: Text("Item 2")),
Center(child: Text("Item 3")),
],
),
),
),
],
),
),
],
),
);
});
}
}
This is what I get:
Thank you for any tips, hints and advice!
Widget showPicker(BuildContext context) {
showModalBottomSheet(
context: context,
builder: (context) {
return Container(
child: Column(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Text('This is a picker'),
Row(
mainAxisSize: MainAxisSize.min,
children: <Widget>[
Expanded(
child: Container(
height: 100,
child: CupertinoPicker(
itemExtent: 30,
onSelectedItemChanged: (int index) {
print(index);
},
children: <Widget>[
Center(child: Text("Item 1")),
Center(child: Text("Item 2")),
Center(child: Text("Item 3")),
],
),
),
),
],
),
],
),
);
});
}
This can solve the issue paste the method, you will get your desired output
