三星Galaxy设备Flutter登录表单自动填充输入首字符后键盘消失

问题描述 #

在搭载Samsung Pass作为自动填充服务的三星Galaxy设备上，运行包含Form与AutofillGroup的Flutter示例应用时，输入首个字符且Samsung Pass无匹配前缀建议的情况下，键盘会突然收起。

复现代码 #

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 Auto Fill Issue'),
    );
  }
}

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

  final String title;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const Text(
              'You have pushed the button this many times:',
            ),
            Form(
              child: AutofillGroup(
                child: Column(
                  children: [
                    TextFormField(
                      autocorrect: false,
                      keyboardType: TextInputType.emailAddress,
                      autofillHints: const [AutofillHints.email],
                      autovalidateMode: AutovalidateMode.onUserInteraction,
                    ),
                    TextFormField(
                      autocorrect: false,
                      keyboardType: TextInputType.text,
                      autofillHints: const [AutofillHints.password],
                      autovalidateMode: AutovalidateMode.onUserInteraction,
                    ),
                  ],
                ),
              ),
            ),
          ],
        ),
      ),
      floatingActionButton: const FloatingActionButton(
        onPressed: TextInput.finishAutofillContext,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}

• 在Pixel模拟器中使用Google作为自动填充服务时无此问题；
• 将Samsung Pass更新至最新版本后问题仍存在；
• 三星Galaxy设备无法禁用Samsung Pass，所有用户都会遭遇该问题。
