Logs
I get this output from IntelliJ:
Launching lib/main.dart on Android SDK built for x86 in debug mode...
Initializing gradle...
Finished with error: Exit code 1 from: /Users/me/Tim/quicktimer/android/gradlew -v:
Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
I've tried quite a lot to solve this. In fact opening the android subfolder in Android Studio works fine and builds the APK without errors, so I really have no idea why this is happening. All the solutions on Google involve running gradle wrapper to regenerate the wrapper that will download the correct version of Gradle or something like that, but I don't know how to run gradle. It isn't in my PATH. I assume it is embedded in IntelliJ somewhere. Bit of a catch-22.
