我希望能够自动捕获或读取短信消息的OTP。我进行了一些测试，例如这段代码：
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Demo Auto OTP'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
TextEditingController _textController = TextEditingController();
String _error;
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Multi-Factor-Authentication"),
),
body: Form(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
mainAxisSize: MainAxisSize.min,
children: [
TextField(
controller: _textController,
autofillHints: [ AutofillHints.oneTimeCode ],
keyboardType: TextInputType.visiblePassword,
maxLength: 6,
maxLengthEnforced: true,
style: TextStyle(fontSize: 32),
),
RaisedButton(
child: Text("Verify"),
onPressed: () => Navigator.of(context).pop(_textController.value.text),
),
],
),
)
);
}
}
这是测试短信：12345是您的登录代码。
