Flutter - String to Int, then int to String

Question

I want to do a simple conversion: Integer to String. Like this.

   String select= (int.parse(widget.data['object']['element'])+1).toString();

But return this error

Unhandled Exception: type 'int' is not a subtype of type 'String'

Anybody know what is the error?

Answer 1

Try this way

int data = int.parse(widget.data['object']['element'] + 1);

String select=data.toString();

Answer 2

I think widget.data['object']['element'] value is already int.

Try

(widget.data['object']['element'] +1).toString();
