In this article we will explore some cool and easy to use bottomsheet widget examples, and see how to integrate them in our apps via step by step examples.

Example 1: Flutter BottomSheet with Adaptive ActionSheet

This example utilizes the flutter_adaptive_action_sheet package.

flutter_adaptive_action_sheet is an action bottom sheet that adapts to the platform (Android/iOS).

For example here is it in Android

Android ActionSheet Example

and here is it in iOS:

iOS Action Sheet Example

Step 1: Create Project

Start by creating a flutter project.

Step 2: Dependencies

Install it by declaring it as a dependency:

adaptive_action_sheet: ^2.0.0

Step 3: Create Action Sheet

Start by importing:

import 'package:adaptive_action_sheet/adaptive_action_sheet.dart';

Instead of using a showModalBottomSheet use showAdaptiveActionSheet Widget:

showAdaptiveActionSheet(
 context: context,
 title: const Text('Title'),
 androidBorderRadius: 30,
 actions: <BottomSheetAction>[
    BottomSheetAction(title: const Text('Item 1'), onPressed: () {}),
    BottomSheetAction(title: const Text('Item 2'), onPressed: () {}),
    BottomSheetAction(title: const Text('Item 3'), onPressed: () {}),
 ],
 cancelAction: CancelAction(title: const Text('Cancel')),// onPressed parameter is optional by default will dismiss the ActionSheet
);

import 'package:flutter/widgets.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Adaptive action sheet Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Adaptive action sheet example'),
      ),
      body: Center(
