I faced this issue in my Flutter app and resolved it by increasing the Gradle JVM memory.

In android/gradle.properties, update the line:

org.gradle.jvmargs=-Xmx512M

to:

org.gradle.jvmargs=-Xmx8G

Then run:

flutter clean
flutter run

If 8 GB isn’t enough, you can increase it further 16GB(e.g., -Xmx16G).
