Flutter微信视频通话插件wechat_video_call的使用

简介

wechat_video_call 是一个用于 Flutter 的插件，它利用 Android 辅助功能服务实现一键拨打微信视频/语音通话的功能。

注意：

• 需要在系统设置中启用应用的辅助功能服务。
• 必须登录微信，并且视频通话的联系人已经在好友列表中。

平台支持

要求

• Flutter >= 3.24.0
• Dart >= 3.5.0
• Android minSdk 24
• Java 17
• Android Gradle Plugin >= 8.1.0
• Gradle wrapper >= 8.3

使用插件

请求辅助权限

bool ret = await WeChatVideoCall.requestAccessibilityPermission();

检查辅助权限

bool ret = await WeChatVideoCall.isAccessibilityPermissionEnabled();

拨打微信视频通话

bool ret = await WeChatVideoCall.videoCall(nickname);

警告

在应用被杀掉后，Android 辅助功能权限会自动禁用，需要重新启用！

import 'package:flutter/material.dart';
import 'package:wechat_video_call/wechat_video_call.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> {
  final _controller = TextEditingController();
  final List<String> _nameList = [];
  bool _accessibilityPermissionEnabled = false;

  [@override](/user/override)
  void initState() {
    super.initState();
    WeChatVideoCall.isAccessibilityPermissionEnabled().then((res) {
      setState(() {
        _accessibilityPermissionEnabled = res;
      });
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('微信视频通话'),
