Type 'String' is not a subtype of type 'int' in type cast

Question

Here's the variable I took

int _bmi = 0;

And this is where I used typecast

actions: [
  TextButton(
    child: const Text('Approve'),
    onPressed: () {
      setState(() {
        int sum = int.parse(massNumber.text) + int.parse(heightNumber.text);
        _bmi = sum.toString() as int;
      });
    },
  ),
]

On running the program, I'm getting an error:

type 'String' is not a subtype of type 'int' in typecast

Answer 1

Actually, what you intended is equal to _bmi = sum

Answer 2

Simply, _bmi = int.parse(massNumber.text) + int.parse(heightNumber.text);
