flutter - “WIDGETS LIBRARY CUGHT CUGHT”即使是新创建的项目，每个项目都不会打印？什么？

Question

在我在一个项目中出错然后打印错误日志后：

I/flutter (13313): ════════════════════════════════════════════════════════════════════════════════════════════════════
I/flutter (13646): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════

I/flutter (13646):   TabNavPage file:///home/lfd/Desktop/works/flutter/trip/flutter_trip/lib/main.dart:11:13

尽管我修复了它并运行成功，但它仍然会打印错误。它也打印在一个新项目中，并且没有文件名 TabNavPage ... 那么错误日志文件存储在哪里？发生了什么？？
