android-studio - Android Studio 中新 Flutter 项目中未解决的引用
问题描述
在 Android Studio 中创建新的 Flutter 项目时，我会立即在 MainActivity.kt 和 GeneratePlouginRegistrant 中获得一系列未解析的引用，如下所示。
如果我随后在 AS 中单独打开 android 模块，这些引用似乎已解决（编辑：虽然如果我返回原始版本则不会）但是我得到以下内容。（我的 Android Gradle 插件目前是 3.5.3 和 Gradle 版本 5.6.2）。
ERROR: Gradle DSL method not found: 'implementation()'
Possible causes:
The project 'android' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Upgrade plugin to version 3.5.3 and sync project
The project 'android' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file
The build file may be missing a Gradle plugin.
Apply Gradle plugin
和这个...

我想知道这些是不是需要解决的问题？
解决方案
如果 Flutter 应用在 Android 上运行正常，则可以忽略错误。您可以运行flutter clean然后flutter pub get刷新 Flutter 项目的 lint 检查。
要使用正确的 lint 检查访问 Android 项目，最好通过Tools > Flutter > Open Android module in Android Studio打开它
