Flutter ADB命令执行插件adb_command_runner的使用

Flutter ADB命令执行插件adb_command_runner的使用

adb_command_runner 插件允许你在运行于Android设备上的Flutter应用中执行带有root权限的ADB命令。

示例代码

以下是一个完整的示例，展示了如何在Flutter应用中使用adb_command_runner插件来执行ADB命令。

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

import 'package:flutter/services.dart';
import 'package:adb_command_runner/adb_command_runner.dart';

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

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

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String _platformVersion = 'Unknown';
  final _adbCommandRunnerPlugin = AdbCommandRunner();

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlatformState();
  }

  // 异步方法初始化平台状态
  Future<void> initPlatformState() async {
    String platformVersion;
    // 可能会失败，所以我们使用try/catch处理PlatformException
    // 我们还处理消息可能返回null的情况
    try {
      platformVersion =
          await _adbCommandRunnerPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }

    // 如果小部件从树中移除，异步平台消息还在飞行中，我们应该丢弃回复而不是调用setState更新我们的非存在的外观。
    if (!mounted) return;

    setState(() {
      _platformVersion = platformVersion;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('插件示例应用'),
        ),
        body: Center(
          child: Text('运行在: $_platformVersion\n'),
        ),
      ),
    );
  }
}

解释

• 导入必要的库：

  import 'package:flutter/material.dart';
  import 'dart:async';
  
  import 'package:flutter/services.dart';
  import 'package:adb_command_runner/adb_command_runner.dart';
  

• 定义主应用类 MyApp：

  class MyApp extends StatefulWidget {
    const MyApp({super.key});
  
    [@override](/user/override)
    State<MyApp> createState() => _MyAppState();
  }
  

• 定义状态类 _MyAppState：

  class _MyAppState extends State<MyApp> {
    String _platformVersion = 'Unknown';
    final _adbCommandRunnerPlugin = AdbCommandRunner();
  
    [@override](/user/override)
    void initState() {
      super.initState();
      initPlatformState();
    }
  

• 初始化平台状态：

  Future<void> initPlatformState() async {
    String platformVersion;
    try {
      platformVersion =
          await _adbCommandRunnerPlugin.getPlatformVersion() ?? 'Unknown platform version';
    } on PlatformException {
      platformVersion = 'Failed to get platform version.';
    }
  
    if (!mounted) return;
  
    setState(() {
      _platformVersion = platformVersion;
    });
  }
  

• 构建应用UI：

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('插件示例应用'),
        ),
        body: Center(
          child: Text('运行在: $_platformVersion\n'),
        ),
      ),
    );
  }
