Flutter Camera Plugin Version 0.8.1 not compatible with AndroidX - flutter

Question

When executing Flutter run I'm getting the following error due to incompatibilities with the Camera plugin library.
Any ideas?

Answer 1

That is a problem with SDK vs plugin compatibility
Go to your build.grade file and check those:
android {
compileSdkVersion 30 // must be 30 for compatibility
defaultConfig {
applicationId "tv.digicash"
minSdkVersion 23
targetSdkVersion 30
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
Check those too in Android Studio at your File > Project Structure (Project and SDKs left menus)
They must be 30 or superior
