string - flutter/Dart : Convert HEX color string to Color?

Question

我们的数据库将颜色保存为像“#AABBCC”这样的String，所以我基本上在寻找这样的函数:Color.parseColor("#AABBCC"); Flutter

Color 类需要这样的 Color(0xFF42A5F5) 所以我需要将 "#AABBCC" 转换为 0xFFAABBCC

Answer 1

/// Construct a color from a hex code string, of the format #RRGGBB.
Color hexToColor(String code) {
  return new Color(int.parse(code.substring(1, 7), radix: 16) + 0xFF000000);
}
