How to round all numbers to 2 in the whole flutter project?

I am working on a flutter app with banking numbers, and therefore only needs two decimal numbers. Is there a way to round every number automatically in my whole project at once ?

The idea is to not use amount.toStringAsFixed(2) all the time.

    Yes you can create one common method for this like below

    Access amountFix every where in your whole code like below:

    void main() {
  print(CommonMethod.amountFix(125.599));
}

    Your common method declare below:

    class CommonMethod {
  static amountFix(double amount) {
    return amount.toStringAsFixed(2);
  }
}

    you can access in widget as well like below:

       Center(
      child: Text(
        CommonMethod.amountFix(125.599),
      ),
    ),

    You can make use of dart extension methods.

    Define the logic for formatting numbers in an extension.

    extension PriceStringExt on num {
  String get priceStr {
    return toStringAsFixed(2);
  }
}

    Use it anywhere in your project.

    int price = 12;
price.priceStr;
