Pattern class abstract

You can construct a Pattern with three different ways:

  • Directly with a Pattern type constructor:
final Pattern p1 = DiagonalStripesLight(bgColor: Colors.yellowAccent, fgColor: Colors.black);

final Pattern p2 = Pattern.fromValues(patternType: PatternType.diagonalLight, bgColor: Colors.yellowAccent, fgColor: Colors.black);
  • From a String representation in the form of "pattern_backgroundHex_foregroundHex":
final Pattern p3 = Pattern.fromString("diagonalLight_ffff00_000000");
