Code sample

import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        // This is the theme of your application.
        //
        // Try running your application with "flutter run". You'll see the
        // application has a blue toolbar. Then, without quitting the app, try
        // changing the primarySwatch below to Colors.green and then invoke
        // "hot reload" (press "r" in the console where you ran "flutter run",
        // or simply save your changes to "hot reload" in a Flutter IDE).
        // Notice that the counter didn't reset back to zero; the application
        // is not restarted.
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  // This widget is the home page of your application. It is stateful, meaning
  // that it has a State object (defined below) that contains fields that affect
  // how it looks.

  // This class is the configuration for the state. It holds the values (in this
  // case the title) provided by the parent (in this case the App widget) and
  // used by the build method of the State. Fields in a Widget subclass are
  // always marked "final".

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      // This call to setState tells the Flutter framework that something has
      // changed in this State, which causes it to rerun the build method below
      // so that the display can reflect the updated values. If we changed
      // _counter without calling setState(), then the build method would not be
      // called again, and so nothing would appear to happen.
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    // This method is rerun every time setState is called, for instance as done
    // by the _incrementCounter method above.
    //
    // The Flutter framework has been optimized to make rerunning build methods
    // fast, so that you can just rebuild anything that needs updating rather
    // than having to individually change instances of widgets.
    return Scaffold(
      appBar: AppBar(
        // Here we take the value from the MyHomePage object that was created by
        // the App.build method, and use it to set our appbar title.
        title: Text(widget.title),
      ),
      body: Center(
        // Center is a layout widget. It takes a single child and positions it
        // in the middle of the parent.
        child: Column(
          // Column is also a layout widget. It takes a list of children and
          // arranges them vertically. By default, it sizes itself to fit its
          // children horizontally, and tries to be as tall as its parent.
          //
          // Invoke "debug painting" (press "p" in the console, choose the
          // "Toggle Debug Paint" action from the Flutter Inspector in Android
          // Studio, or the "Toggle Debug Paint" command in Visual Studio Code)
          // to see the wireframe for each widget.
          //
          // Column has various properties to control how it sizes itself and
          // how it positions its children. Here we use mainAxisAlignment to
          // center the children vertically; the main axis here is the vertical
          // axis because Columns are vertical (the cross axis would be
          // horizontal).
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            TextField(),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const Icon(Icons.add),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );

Can anyone confirm if this is a regression?

[AlexV525]

We previously have the quite same issue #108124. The corresponding fix cc62a5b only lands in master, might require a cherry-pick for this? cc @dkwingsmt

[AlexV525]

Can everyone facing the issue verify if it's still reproducible on the master channel?

i keep getting this error on master:
Launching lib/main.dart on iPhone 13 Pro in debug mode... Running Xcode build... └─Compiling, linking and signing... 10.8s Xcode build done. 34.2s remote notifications are not supported in the simulator [VERBOSE-2:dart_isolate.cc(143)] Could not prepare isolate. [VERBOSE-2:runtime_controller.cc(386)] Could not create root isolate. [VERBOSE-2:shell.cc(610)] Could not launch engine with configuration.

am getting the issue here with flutter 3.3 stable:

import 'package:flutter/material.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';

import '../../../../../constants/const.dart';

class BaseBottomSheet extends StatelessWidget {
  final List<Widget> children;
  final double bottomSheetsHeight;
  const BaseBottomSheet(
      {Key? key,
      required this.children,
      this.bottomSheetsHeight = bottomSheetHeight})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Material(
      color: Colors.white,
      elevation: 5,
      child: SizedBox(
        height: bottomSheetsHeight.h,
        width: bottomSheetWidth(context),
        child: SingleChildScrollView(
          child: Column(
            children: children,
          ),
        ),
      ),
    );
  }
}

it keeps crashing when the BaseBottomSheet is active if i comment out the hight and width, once in the page if i add static values to the width and hight it works with hot reload. When restarting it , it crashes again.
