toHex method

String toHex({
  1. bool leadingHashSign = true,
})

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

Implementation

String toHex({bool leadingHashSign = true}) => '${leadingHashSign ? '#' : ''}'
    '${(a * 255).toInt().toRadixString(16).padLeft(2, '0')}'
    '${(r * 255).toInt().toRadixString(16).padLeft(2, '0')}'
    '${(g * 255).toInt().toRadixString(16).padLeft(2, '0')}'
    '${(b * 255).toInt().toRadixString(16).padLeft(2, '0')}';
