Fui executar o flutter run e apareceu isso
FAILURE: Build failed with an exception.
What went wrong: Execution failed for task ':app:compileDebugKotlin'.
Kotlin could not find the required JDK tools in the Java installation 'C:\Program Files\Java\jre1.8.0_291' used by Gradle. Make sure Gradle is running on a JDK, not JRE.
Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
