The first step would be to import a simple library as given below:  Code : -  import ‘package:Flutter/foundation.dart’ as Foundation;
Then, we can use kReleaseMode as shown below: -  Code: -  If(Foundation.kReleaseMode){
print(‘In release mode’);
} else{
print(‘In debgugging mode’);
}  The asserts can be used to manually create an “is debug mode,” we should always avoid that. The issue with asserts is that the isInReleaseMode boolean value is not constant, so while shipping our application, both the dev as well as release mode codes are also shipped along with it. Over here the kReleaseMode is a constant, therefore the compiler can remove unused code correctly.  Now we will see the Flutter interview question and answers for developers. These Flutter and dart interview questions can be asked to you if you are willing to join a company as a Flutter developer.
