Answer 1

I had the same problem today.
The only solution for me, was this.
Go to your pubspec.yaml
delete your share_plus line, and put share_plus: ^4.0.4 (or latest version from pub.dev
ctrl+s
flutter run
enjoy

Answer 2

I had the same problem yesterday, although I do not quite remember how I solved it. Let's try to go through the standard:
Wipe all flutter cache (flutter clean) and upgrade to latest flutter and dart.
Update your plugins to the latest version.
I'll give you my android/build.gradle file below, compare.
I will also show you my android/app/build.gradle file, look for the lines where kotlin is written, its version, import, etc.
I won’t say, but as far as I remember, I had this problem when I used one of the translation plugins, this plugin added an additional translate method to the String object, it was displayed correctly in the code, but when launched it gave an error related to Kotlin. Example:
String text;
print(text.translate); //Error for no apparent reason
So check your code carefully.
Pay special attention to this warning from your error message: "Type mismatch: inferred type is String? but String was expected". Try to find this gap in the newly written functionality.
