colorToHex function

String? colorToHex(
  1. Color? color, {
  2. bool leadingHashSign = true,
})

Prefixes a hash sign if leadingHashSign is set to true (default is true).

Implementation

String? colorToHex(Color? color, {bool leadingHashSign = true}) {
  if (color == null) return null;
  return '${leadingHashSign ? '#' : ''}'
      '${color.alpha.toRadixString(16)}'
      '${color.red.toRadixString(16)}'
      '${color.green.toRadixString(16)}'
      '${color.blue.toRadixString(16)}';
}
