Question

我是Flutter的新手，今天我被困在一个问题上。我无法调试我的应用，因为它说参数格式不正确

Parameter format not correct -

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageDebug'.
> Several variant outputs are configured to use the same file name "resources-debug.ap_", filters : MAIN:MAIN

这是我扑扑的医生

我到处都在寻找答案，但这些答案不适用于我的情况。大多数解决方案都建议更改环境路径。这是我的路径：C：\ src \ flutter \ bin 注意：我使用的是VSCode

请帮助..谢谢！

Answer 1

当我观察您的Flutter Doctor时，已经定义未配置 Android工具链和 Android Studio 。所以。请按照以下步骤操作。要解决 Android工具链，请运行“ flutter doctor --android-licenses” 。对于“ Android Studio”，请转到Android Studio->文件->设置->插件->安装Flutter 。在安装flutter的同时，还要求安装dart，单击“确定”，安装后，它将要求重新启动Android Studio。重新启动后转到Flutter终端并运行Flutter Doctor，现在您已经解决了上述问题。只是忽略了最后一个问题，因为它只是表明没有设备连接。

您可以在Windows和Mac的Android Studio中运行Flutter。
