Flutter Modal Bottom Sheet Code Implement Code File Conclusion

Flutter :

“ Flutter is Google’s UI toolkit that helps you build beautiful and natively combined applications for mobile, web, and desktop in a single codebase in record time It means that you can use one programming language and one codebase to create two different apps (for iOS and Android)”.

Modal Bottom Sheet :

The bottom sheet material is a very good component given by design. It is like a dialog that is open from the bottom. We use the sheet below when we have to show some options for the user to proceed. And here you can use any widget as per your requirement.

Two Required Properties of the Modal Bottom Sheet :

BuildContext: The build context for a particular widget can change the location over time. Because it helps the creation method to determine which widget it is going to pull and it also helps in determining the position of the widget to be pulled in the widget tree. WidgetBuilder: The builder widget needs to pass a widget, but only has a function that returns the widget.

Some Optional Properties of the Modal Bottom Sheet :

shape: Using shape properties, we can give a circular border and color of the border according to our own. background: Using shape properties, we can give a circular border and color of the border according to our own. elevation: The elevation property is used to raise the shadow of the bottom sheet and it is an optional property.

Demo Module :

Code Implementation :

Create a new dart file called modal_bottom_sheet.dart inside the lib folder.

First of all, we will create one button on the modal bottom sheet page screen. And we will open the sheet at the click.

Now, at the click of a button, we will show the bottom sheet in which the column has been taken inside the bottom sheet and used the List Tile widget inside the column widget, in which some images and titles are displayed.

Let us understand this with the help of a reference.

showModalBottomSheet(

context: context,

builder: (context) {

return Column(

mainAxisSize: MainAxisSize.min,

children: <Widget>[

ListTile(

leading: new Icon(Icons.photo),

title: new Text('Photo'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.music_note),

title: new Text('Music'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.videocam),

title: new Text('Video'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.share),

title: new Text('Share'),

onTap: () {

Navigator.pop(context);

},

),

],

);

});

When we run the application, we ought to get the screen’s output like the underneath screen capture.

Code File:

import 'package:flutter/material.dart'; class ModalBottomSheet extends StatefulWidget {

@override

_ModalBottomSheetState createState() => _ModalBottomSheetState();

} class _ModalBottomSheetState extends State<ModalBottomSheet> {

@override

Widget build(BuildContext context) {

return Scaffold(

appBar: AppBar(

title: Text(

'Modal Bottom Sheet',

style: TextStyle(color: Colors.white),

),

centerTitle: true,

),

body: Container(

alignment: Alignment.center,

child: Column(

mainAxisAlignment: MainAxisAlignment.center,

children: [

Text(

"MODAL BOTTOM SHEET EXAMPLE",

style: TextStyle(

fontStyle: FontStyle.italic,

letterSpacing: 0.4,

fontWeight: FontWeight.w600),

),

SizedBox(

height: 20,

),

RaisedButton(

shape: RoundedRectangleBorder(

borderRadius: BorderRadius.all(Radius.circular(10.0))),

onPressed: () {

showModalBottomSheet(

context: context,

builder: (context) {

return Column(

mainAxisSize: MainAxisSize.min,

children: <Widget>[

ListTile(

leading: new Icon(Icons.photo),

title: new Text('Photo'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.music_note),

title: new Text('Music'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.videocam),

title: new Text('Video'),

onTap: () {

Navigator.pop(context);

},

),

ListTile(

leading: new Icon(Icons.share),

title: new Text('Share'),

onTap: () {

Navigator.pop(context);

},

),

],

);

});

},

padding:

EdgeInsets.only(left: 30, right: 30, top: 15, bottom: 15),

color: Colors.pink,

'Click Me',
