Flutter日志记录插件tiny_logger的使用

Flutter日志记录插件tiny_logger的使用

一个用于Flutter项目的日志记录工具。

使用方法

要记录一条消息，你可以这样做：

import 'package:tiny_logger/tiny_logger.dart';

log.debug('...');
log.warn('...');
log.error('...');

最好在你的analysis_options.yaml文件中配合使用avoid_print规则：

linter:
  rules:
    - avoid_print

要显示内置日志查看器，可以使用LogView组件：

bool _showLog = false;

[@override](/user/override)
Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(title: Text('Tiny Logger Example')),
    body: Stack(
      children: [
        Center(child: Text('Hello World!')),
        
        if (_showLog)
          LogView(
            onClose: () => setState(() => _showLog = false),
          ),
      ],
    ),
  );
}

示例

示例代码

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

void main() {
  // 捕获Flutter错误并记录到日志
  FlutterError.onError = (details) {
    log.error(details);
    FlutterError.dumpErrorToConsole(details);
  };
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Tiny Logger Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key key}) : super(key: key);

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

class _MyHomePageState extends State<MyHomePage> {
  bool _showLog = false;

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Tiny Logger Example'),
      ),
      body: Stack(
        children: [
          Center(
            child: IntrinsicWidth(
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.stretch,
                mainAxisSize: MainAxisSize.min,
                children: [
                  MaterialButton(
                    color: Colors.blue,
                    onPressed: () {
                      // 记录调试信息
                      log.debug('This is a debug message!');
                    },
                    child: const Text('Log Debug'),
                  ),
                  MaterialButton(
                    color: Colors.yellow,
                    onPressed: () {
                      // 记录警告信息
                      log.warn('This is a warning!');
                    },
                    child: const Text('Log Warning'),
                  ),
                  MaterialButton(
                    color: Colors.red,
                    onPressed: () {
                      // 记录错误信息
                      log.error('This is an error!');
                    },
                    child: const Text('Log Error'),
                  ),
                  MaterialButton(
                    color: Colors.red,
                    onPressed: () {
                      // 抛出异常
                      throw UnimplementedError('Example error');

                    child: const Text('Throw Error'),
                  ),
                  const SizedBox(height: 20),
                  MaterialButton(
                    color: Colors.red,
                    onPressed: () => setState(() => _showLog = true),
                    child: const Text('SHOW LOG'),
                  ),
                ],
              ),
            ),
          ),
          // 显示日志视图
          if (_showLog)
            LogView(
              onClose: () => setState(() => _showLog = false),
            ),
        ],
