Guys am trying to convert a list of strings into a widget in flutter, in the code itself it's not showing any error, but emulator is saying this -> type 'List' is not a subtype of type 'String' in type cast. What am i doing wrong though?

I also added an image, so you guys can see.

Answer 1

Change Questions(questions[_indexQuestion]["answer"] as String), to Questions(questions[_indexQuestion]["questionText"] as String),
