如何在Android Studio中使用Flutter RP2清理构建? [英] How to clean your build with Flutter RP2 in Android Studio?

问题描述

在使用Android Studio 3.1.4的FLutter Release Preview 2发行版中，当我使用命令stop'main.dart'(命令f2)从Android Studio停止程序，然后执行运行时，我的项目出现了零星的构建问题main.dart'(^ R)我收到以下错误.但是，如果我完全关闭Android Studio并再次打开该项目，它将编译并正确运行而不会出现错误.我想知道是否有一种方法可以清理项目以提高关闭和打开Android Studio的效率，这与Flutter热重装有点反作用.

With the release of FLutter Release Preview 2 using Android Studio 3.1.4 my project has sporadic build issues when I stop the program from Android Studio with the command stop 'main.dart' (command f2) and then do a run 'main.dart' (^R) I get the error listed below. Yet if I totally close Android Studio and open the project again, it compiles and runs correctly without the error. I'm wondering if there is a way to clean the project to elevate having to close and open Android Studio, this is sort of counter productive to Flutter hot reload.

这是我收到的Android Studio错误:

Here's the Android Studio error that I get:

您可以忽略错误日志的以下部分(上面的斜体字)，因为在成功执行程序时会发生这种情况.

You can ignore the following part of the error log (in italics above), as this occurs on a successful execution of the program.
