Flutter 项目中 gradle Android Studio 中的弃用警告

Question

I have created a Flutter project in Android Studio (Bumblebee | 2021.1.1 Patch 3). When I open the android folder in a seperate window, when the gradle syncing is being executed, it fails with the message Gradle project sync failed. Basic functionality(eg editing,debugging) Gradle project sync failed. Basic functionality(eg editing,debugging) will not work properly. I ran ./gradlew --warning-mode all in the command line and it's output is

> Task :help

Welcome to Gradle 6.7.

To run a build, run gradlew <task> ...

To see a list of available tasks, run gradlew tasks

To see a list of command-line options, run gradlew --help

To see more detail about a task, run gradlew help --task <task>

For troubleshooting, visit https://help.gradle.org

The last warning is due to system_alert_window (flutter)plugin that I am using. But these deprecation warnings are causing issues in Android Studio editor so that I am unable to use code completion feature. I don't know why is this happening, since these are only warning messages.

My gradle version is 6.7 and android-gradle version is 4.1.0 .

Can anyone please help?

Step 2:

Disable android.enableR8=true by adding a # in front:

#android.enableR8=true

Alternatively, you can swap out the R8 for D8, The build system changed to using D8 instead of R8.

android.enableD8=true
