This is my code:
String formatMinute() {
if (int.parse('${_time.minute}') < 10) {
String newMin = '${_time.minute}' + '0';
return newMin;
}
}
I would like the result of formatMinute() to be in a statefulWidget. Here is my code in the statefulWidget.
Text('Time selected: ${_time.hour}:${_time.minute}'),
I would like "${_time.minute}" to be replaced with the result of formatMinute(). Is this possible? Thanks for your time and help!
You should try using an extension method! (https://dart.dev/guides/language/extension-methods)
Keep in mind that
TimeOfDay _time = new TimeOfDay.now() will have the properties hour and minute as int, so your extension method should also be on an int:
extension NumberFormat on int {
String formatMinute() {
if (this < 10) {
String newMin = '0' + this.toString();
return newMin;
}
return this.toString();
}
}
And then, this should go inside your widget:
Text('Time selected: ${_time.hour}:${_time.minute.formatMinute()}')
Notice that the extension method is something like a class, so you need to declare it outside your widget class.
You should update your pubspec to remove any warning too:
environment:
sdk: ">=2.6.0 <3.0.0"
In Dart, you can put any code including function calls inside string interpolation. So this is perfectly valid:
Text('Time selected: ${_time.hour}:${formatMinute()}')
Also note that formatMinute implementation could simplified:
String formatMinute() => _time.minute.padLeft(2, '0');
