Flutter error: The argument type 'Color Function(String)' can't be assigned to the pa-CodePudding

I'm having the error The argument type 'Color Function(String)' can't be assigned to the parameter type 'dynamic Function(dynamic)' in this line:

final colors = data.map(getColorFromCode);

Here is the data:

late final data = [
    widget.result,
    widget.result2,
    widget.result3,
  ];

Here is the function getColorFromCode:

Color getColorFromCode(String code) {
  if (code.contains('A') && code.contains('P')) return Colors.brown;
  if (code.contains('A') && code.contains('pp')) return Colors.black;
  if (code.contains('aa')) return Colors.white;
  return Colors.black;
}

How to solve this error? If you need any additional details feel free to ask.

CodePudding user response：

try giving the data type to you data list

like this

final List<String> data = [widget.result,
widget.result2,
widget.result3,];
