Execution failed for task ':gradle:compileKotlin' Cannot resolve external dependency com.android.tools.build because no repositories are defined

Question

After upgrading from Flutter 3.27.1 to 3.29.0, I can no longer run flutter apps on my computer. Even creating a new project:

-> mkdir flutt
-> cd flut
-> flutter create . --platforms=android
-> flutter run

FAILURE: Build failed with an exception.



* What went wrong:
Execution failed for task ':gradle:compileKotlin'.
> Could not resolve all files for configuration ':gradle:compileClasspath'.
   > Cannot resolve external dependency com.android.tools.build:gradle:8.7.3 because no repositories are defined.
     Required by:
         project :gradle
   > Cannot resolve external dependency org.jetbrains.kotlin:kotlin-stdlib:1.9.24 because no repositories are defined.

   > Cannot resolve external dependency org.jetbrains.kotlin:kotlin-reflect:1.9.24 because no repositories are defined.

I edited ~/snap/flutter/common/flutter/packages/flutter_tools/gradle/build.gradle.kts

to add

repositories {
    google()
    mavenCentral()
}

and it now works.
