        ),
        body: ListView(
          children: <Widget>[
            Container(color: baseColor, height: 50),
            Container(color: baseColor.darken(0.2), height: 50),
            Container(color: baseColor.lighten(0.2), height: 50),
            Container(color: baseColor.invert(), height: 50),
            Container(color: baseColor.compliment(), height: 50),
            Container(color: baseColor.desaturate(0.2), height: 50),
            Container(color: baseColor.saturate(0.2), height: 50),
            Container(color: baseColor.mix(mixColor, 0.5), height: 50),
            Container(color: baseColor.whiten(0.5), height: 50),
            Container(color: baseColor.tone(0.5), height: 50),
            Container(color: baseColor.blacken(0.5), height: 50),

    );
  }
}

Methods

The extension adds the following methods:

• darken([double amount = .5]): Darkens the color by the provided amount (0-1), defaulting to 50%.
• lighten([double amount = .5]): Lightens the color by the provided amount (0-1), defaulting to 50%.
• invert(): Inverts a color, producing its "negative". It does not preserve lightness. If you want to do that, use the compliment method.
• compliment(): Gets the complimentary (opposite on the color wheel) of a color. This is like inverting, however it keeps the same lightness value.
• desaturate([double amount = .5]): Desaturates a color by the provided amount (0-1), defaulting to 50%.
• saturate([double amount = .5]): Saturates a color by the provided amount (0-1), defaulting to 50%.
• mix(Color another, [double amount = 0.5]): Mixes a color with another one by the provided amount (0-1), defaulting to 50%.
• whiten([double amount = 0.5]): Whitens a color by mixing it with white by the provided amount (0-1), defaulting to 50%.
• tone([double amount = 0.5]): Tones down a color by mixing it with grey by the provided amount (0-1), defaulting to 50%.
• blacken([double amount = 0.5]): Blackens a color by mixing it with black by the provided amount (0-1), defaulting to 50%.
• isDark: Checks if a color is considered dark using the luminance.
• isBright: Checks if a color is considered bright.
