How to remove trailing zeros using Dart
I made regular expression pattern for that feature.
double num = 12.50; // 12.5
double num2 = 12.0; // 12
double num3 = 1000; // 1000
RegExp regex = RegExp(r'([.]*0)(?!.*\d)');
String s = num.toString().replaceAll(regex, '');
UPDATE
A better approach, just use this method:
String removeDecimalZeroFormat(double n) {
return n.toStringAsFixed(n.truncateToDouble() == n ? 0 : 1);
}

This meets the requirements:
double x = 12.0;
double y = 12.5;
print(x.toString().replaceAll(RegExp(r'.0'), ''));
print(y.toString().replaceAll(RegExp(r'.0'), ''));
X Output: 12
Y Output: 12.5
