data[widget.CurrentIndex].sentence // dont display the next
level image. if the
asnwer is correct than the button will show.
String joinedWords =
selectedWords.join(" ").toString();
String _setRatingOnAlert() {
//print(controller.duration?.inSeconds);
print(data![widget.CurrentIndex].timer);
print(data[widget.CurrentIndex].level);
print(joinedWords);
print(data[widget.CurrentIndex].sentence);
print(widget.CurrentIndex);
if (joinedWords ==
data[widget.CurrentIndex].sentence) {
starsRating = 'assets/threestars_small.png';

Answer 1

use ternary operator in this case.
bool answer = false;
//do some operation with answer;
(answer)? ShowImage():Container();
Widget showImage(){
return Container(
child: Image.network(
'imagePath',
fit: BoxFit.fitWidth,
);
}

Answer 2

isTrue? Image.asset():Container()
