Flutter日志着色插件colorize_logger的使用

中文说明

colorize_logger 是一个为 Flutter 设计的日志系统，可以在调试模式下打印日志，在发布模式下关闭日志。

使用方法

在 main.dart 文件中配置 colorize_logger。以下是一个完整的示例代码：

import 'dart:io';

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

void main() {
  // 判断当前是否为发布模式
  if (Logger.isReleaseMode()) {
    /// 使用文件记录日志
    Directory directory = await getApplicationDocumentsDirectory();
    final currentDate = DateTime.now();
    final fileName = '${currentDate.year}-${currentDate.month}-${currentDate.day}-logs.txt';
    Logger.client = FileLoggerClient(filePath: '${directory.path}/$fileName');

    /// 使用Sentry记录错误
    // await SentryFlutter.init(
    //   (options) {
    //     options.dsn = 'https://example@sentry.io/add-your-dsn-here';
    //   },
    // );
    // Logger.client = SentryLoggerClient();
  } else {
    /// 调试模式
    Logger.client = ColorizeLoggerClient();
  }

  // 启动应用
  runApp(MyApp());
}

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

class MyHomePage extends StatefulWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

  [@override](/user/override)
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

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

    // 输出不同级别的日志
    Logger.info('info');
    Logger.warning('warning', tag: '_MyHomePageState');
    Logger.fatal('fatal');
    Logger.error('error');
  }

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            Text('You have pushed the button this many times:'),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: Icon(Icons.add),
      ),
    );
  }
}
