I have a fresh installation of Android Studio and Flutter. flutter doctor runs without any major errors.
When I try to run a new project, I get a long list of errors inside Flutter's own files, like
'Offset' isn't a type and Error: The getter 'CaretMetrics' isn't defined.
Things I have already tried:
- A full, clean reinstall of both Android Studio and the Flutter SDK.
- Running flutter clean and flutter pub get.
- Creating multiple new emulators.
- Setting the emulator graphics to 'Software - GLES 2.0'.
- Deleting all .android, .gradle, and AppData folders.
- Updating the system PATH variable.
Minimal Reproducible Example
This error happens with the default "Counter App" that is created when you run flutter create
. The code is the standard main.dart
file:
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
useMaterial3: true,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
void _incrementCounter() {
setState(() {
_counter++;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
backgroundColor: Theme.of(context).colorScheme.inversePrimary,
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
const Text(
'You have pushed the button this many times:',
),
Text(
'$_counter',
style: Theme.of(context).textTheme.headlineMedium,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: const Icon(Icons.add),
),
);
}
}
