Flutter集成TAR SDK插件tar_sdk_flutter的使用

Flutter集成TAR SDK插件tar_sdk_flutter的使用

本项目是一个用于Flutter的新插件项目。它是一个专门的插件包，包括针对Android和/或iOS平台的特定实现代码。

开始使用

如果您刚开始学习Flutter开发，可以查看官方文档，其中包含教程、示例、移动开发指南以及完整的API引用。

示例代码

以下是使用tar_sdk_flutter插件的完整示例代码：

import 'package:flutter/material.dart';
import 'dart:async';
import 'package:tar_sdk_flutter/tar_sdk_flutter.dart';
import 'package:tar_sdk_flutter/tar_sdk_flutter_method_channel.dart';
import 'package:tar_sdk_flutter/tar_sdk_flutter_platform_interface.dart';
import 'package:flutter_dotenv/flutter_dotenv.dart';

void main() async {
  // 加载环境变量文件
  await dotenv.load(fileName: '.env');
  runApp(const MyApp());
}

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

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

class _MyAppState extends State<MyApp> {
  CancelListening cancelListening = () {};

  final _tarSdkFlutterPlugin = TarSdkFlutter();

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

  // 平台消息是异步的，因此我们在异步方法中进行初始化
  Future<void> initPlatformState() async {
    // 如果在异步平台消息传输期间小部件从树中移除，则我们希望丢弃回复而不是调用setState来更新我们的非存在外观。
    if (!mounted) return;

    setState(() {});
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('TAR SDK 示例应用'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: [
              // 按钮用于打开TAR SDK
              TextButton(
                onPressed: () async {
                  var isSupported = await _tarSdkFlutterPlugin.isSupported();
                  if (isSupported) {
                    // 获取API密钥
                    var apiKey = dotenv.env['TAR_APIKEY'] ?? '';
