i have a working flutter project but when i install agora RTC package it gives Execution failed for task ':agora_rtc_engine:compileDebugKotlin'. error. I'm not even using the package yet, i tried setting up the permissions and all the instructions in the readme section but i think the issue is with the package itself, also my flutter project is null-safety migrated and it's working so I'm sure there's nothing wrong with my project.
I'm not using the package yet. It gives an error just by installing it.
here is the app/gradle.build:
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}

CodePudding user response：
i found the issue, it's because i was using flutter dev channel, if you have the same issue, make sure you are using the latest flutter stable version, to do this:
- run
flutter channel stable
make sure your pubspec.yaml file has changed the flutter version to the stable version,
- run
flutter clean - run
flutter run
you may get an error from flutter lint package, i solved this issue by removing it.
