Performance

1. Offline mode / downloads code.

On Windows

Edit FLUTTER_PROJ_DIR/android/gradlew.bat

Add switch --offline in %JAVA_EXEC%

  @rem Execute Gradle
  "%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% \
  %GRADLE_OPTS% "-Dorg.gradle.appname=%APP_BASE_NAME%" \
  -classpath "%CLASSPATH%" \
  org.gradle.wrapper.GradleWrapperMain %CMD_LINE_ARGS% --offline

On Nix

Edit FLUTTER_PROJ_DIR/android/gradlew

Add switch --offline in $JAVACMD

  exec "$JAVACMD" "${JVM_OPTS[@]}" -classpath "$CLASSPATH" \
  org.gradle.wrapper.GradleWrapperMain "$@" --offline

2. Gradle Settings `gradle.properties`

org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8
android.useAndroidX=true

Print version during build

Add the following line to android/build.gradle

println(com.android.tools.r8.Version.getVersionString())

And run
