Flutter的异常打印信息过滤，快速定位代码异常

项目地址

基于dart官方stack_trace开发

stack_trace打印

I/flutter ( 3068): package:example/ui/login_page.dart 135:31                  _LoginPageState.buildBody.

使用方法

import 'package:flutter_stack_trace/flutter_stack_trace.dart';

//default simple mode
void main() => FlutterChain.capture(
      () {
        runApp(MyApp());
      },
    );

//just print in debug mode
//isShowTime default true
FlutterChain.print("test",isShowTime: false);
