toHex method
Prefixes a hash sign if leadingHashSign
is set to true
(default is true
).
Implementation
String toHex({bool leadingHashSign = true, bool withAlpha = false}) =>
'${leadingHashSign ? '#' : ''}'
'${withAlpha ? alpha.toRadixString(16).padLeft(2, '0') : ''}'
'${red.toRadixString(16).padLeft(2, '0')}'
'${green.toRadixString(16).padLeft(2, '0')}'
'${blue.toRadixString(16).padLeft(2, '0')}';
