  1. Color c
)

获取颜色的argb

Implementation

static List<dynamic> getRGBOFromColor(Color c) {
  // 提取RGB分量（0-255整数）
  int r = c.red;//(c.r).round() & 0xff;
  int g = c.green;//(c.g).round() & 0xff;
  int b = c.blue;//(c.b).round() & 0xff;
  // 提取透明度（0.0-1.0）
  double o = c.opacity;//.a  / 255.0;
  // print('r ${c.red} g $g b $b o $o  ${c.a}. ${c.opacity}');
  return [r, g, b,o];
