I am currently working in a page where I have to show a list of apps in the device which should be half a screen only, for that i have a used a bottom drawer widget to display that , the main problem is every time i open the app it needs to get pulled, i don't want to do it so can some help me to display the apps without pulling the bottom drawer widget ? or else is there any other widget to do that ?

CodePudding user response：

You can use DraggableScrollableSheet with minChildSize: .5, on this case.

 return Scaffold(
      bottomNavigationBar: DraggableScrollableSheet(
        minChildSize: .5,
        maxChildSize: 1,
        builder: (context, scrollController) {
          return ListView.builder(
            controller: scrollController,
            itemCount: 25,
            itemBuilder: (BuildContext context, int index) {
              return ListTile(title: Text('Item $index'));
            },
          );
        },
      ),

You can try bottom modal sheet or draggableScrollableSheet which has a min size

import 'package:flutter/material.dart';

void main() => runApp(const MyApp());

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  static const String _title = 'Flutter Code Sample';

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: _title,
      home: Scaffold(
        appBar: AppBar(title: const Text(_title)),
        body: const MyStatelessWidget(),
      ),
    );
  }
}

class MyStatelessWidget extends StatelessWidget {
  const MyStatelessWidget({Key? key}) : super(key: key);

      body: SizedBox.expand(
        child: DraggableScrollableSheet(

            return Container(
              color: Colors.blue[100],
              child: ListView.builder(
                controller: scrollController,
                itemCount: 25,
                itemBuilder: (BuildContext context, int index) {
