Trying to add two math results $roundoneresult and $roundtworesult together as visable text as a total in Flutter

I tried to add the text as below to make it work but it just shows =(sum of round 1) +(sum of round 2) but doesnt add them up: CODE

            Text(
              "Result n Round 1: $roundOneResult and Round 2: $roundTwoResult Total = $roundOneResult + $roundTwoResult",
              textAlign: TextAlign.center,
              style: const TextStyle(
                fontSize: 30,
              ),
            ),
          ],
        ),
      ),
    );
  }
}

I tried the above and was expectingenter image description here

more code sample if you need a reference thanks all:

              children: <Widget>[
                ElevatedButton(

                  onPressed: () {
                    setState(() {
                      roundOneFields.forEach((e) =>
                          roundOneResult = roundOneResult + int.parse(e.text));
                      roundTwoFields.forEach((e) => roundTwoResult =
                          roundTwoResult + int.parse(e.text.toString()));
                    });
                  },
                )
              ],
            ),
            Text(
              "Result n Round 1: $roundOneResult and Round 2: $roundTwoResult Total = $roundOneResult + $roundTwoResult",
              textAlign: TextAlign.center,
              style: const TextStyle(

    this problem arose because you added val 1 and val 2 with ‘+’ which is working as a String. try this:

                    Text(
                "Result n Round 1: $roundOneResult and Round 2: 
                 $roundTwoResult Total = ${roundOneResult + 
                 roundTwoResult}",
                 textAlign: TextAlign.center,
                 style: const TextStyle(
                 fontSize: 30,
                ),
              ),

    if. it’s worked then mark it as solved.

    The other answer is also correct. Anotherway,

    // Calculate the total sum
double totalSum = roundOneResult + roundTwoResult;

// ...

Text(
  "Result n Round 1: $roundOneResult and Round 2: $roundTwoResult Total = $totalSum",
  textAlign: TextAlign.center,
  style: const TextStyle(
    fontSize: 30,
  ),
),
