One: problem description
In the current development environment, I open an Android project of a Flutter project, and after Android Studio automatically downloads the gradle configuration file, the prompt content is shown in the figure below.
Prompt content:
Gradle project sync failed.Basic functionality(e.g.editing,debugging) will not work properly，
The translated meaning is that the Gradle project failed to sync. Basic functions (such as editing, debugging) will not work properly.
Then I tried various attempts with the content of the prompt, what project to configure maven in the build.gradlefile , or download the offline gradle package, or gradle.propertiesadd it to the file, android.enableR8 = trueetc. All failed, there is no way, then check what the problem is.

then click in sequence File - Sync Project with Gradle Files, and wait for Android Studio to automatically download the relevant configuration, as shown in the figure below
The final rendering is as follows .
The content of the prompt has disappeared, and you're done. It would be great if your problem was solved in this way.
