To round a double in Dart to a given degree of precision AFTER the decimal point, you can use built-in solution in dart toStringAsFixed() method, but you have to convert it back to double

void main() {
  double step1 = 1/3;  
  print(step1); // 0.3333333333333333
  
  String step2 = step1.toStringAsFixed(2); 
  print(step2); // 0.33 
  
  double step3 = double.parse(step2);
  print(step3); // 0.33
}
