Flutter性能监控插件fl_umeng_apm的使用

Flutter性能监控插件fl_umeng_apm的使用

初始化友盟

在使用 fl_umeng_apm 插件之前，需要先初始化友盟。可以通过以下代码实现：

Future<void> initState() async {
  /// 注册友盟性能监测
  final bool? data = await FlUMengAPM().init();

  /// 初始化APM后再 初始化UMeng
  print('UMeng 初始化成功 = $data');
}

设置版本号

可以设置应用的版本号，例如从 1.0.0 更新到 1.1.1。

void fun() async {
  /// 设置版本号
  final bool data =
  await FlUMengAPM().setAppVersion('1.0.0', '1.1.1', '20');
  print('setAppVersion  $data');
}

下面是一个完整的示例代码，包含了上述功能：

import 'package:flutter/material.dart';
import 'package:fl_umeng/fl_umeng.dart';
import 'package:fl_umeng_apm/fl_umeng_apm.dart';

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

class MyApp extends StatelessWidget {
  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter UMeng APM Example',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  [@override](/user/override)
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String text = '';

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

  /// 注册友盟性能检测
  Future<void> init() async {
    /// 注册友盟
    debugPrint('注册友盟');
    final bool data = await FlUMeng().init(
        androidAppKey: '5f8fe2abfac901c19a8642e',
        iosAppKey: '5f8fe4d4c1122b44acfc7aa7',
        channel: 'channel');
    debugPrint('Umeng 初始化成功 = $data');
    await Flumeng().setLogEnabled(true);

    /// 注册友盟性能检测
    debugPrint('注册友盟性能检测');
    final bool value = await FlUMengAPM().init();
    debugPrint('Umeng apm 初始化成功 = $value');

    /// 设置版本号
    final bool versionData = await FlUMengAPM().setAppVersion('1.0.0', '1.1.1', '20');
    debugPrint('setAppVersion  $versionData');
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(

          ElevatedButton(
            onPressed: () async {
              final bool data =
                  await FlUMengAPM().setCustomLog('key', 'type');
              text = 'setCustomLog  $data';
              setState(() {});
            },
            child: Text('setCustomLog'),
