Example

CssLike.linearGradient()

🎨 Gradient at the default angle

with CSS:

background: linear-gradient(#e66465, #9198e5);

with Flutter:

Container(
  height: 300,
  width: 300,
  decoration: BoxDecoration(
    gradient: linearGradient(null, ['#e66465', '#9198e5']),
  ),
);

*Note: If the first argument is null, a 180 degree angular gradient is created.

🎨 Gradient at a 45-degree angle

with CSS:

background: linear-gradient(45deg, red, blue);

with Flutter:

Container(
  height: 300,
  width: 300,
  decoration: BoxDecoration(
    gradient: linearGradient(45, ['red', 'blue']),
  ),
);

*Note: The color argument can use X11/CSS3 color names.

🎨 Gradient that starts at 60% of the gradient line

with CSS:

background: linear-gradient(135deg, orange, orange 60%, cyan);

with Flutter:

Container(
  height: 300,
  width: 300,
  decoration: BoxDecoration(
    gradient: linearGradient(135, ['orange', 'orange 60%', 'cyan']),
  ),
);

*Note: You can add a color-stop points using the stop argument. It can be used with % such as 'orange 60%'.

🎨 Gradient with multi-position color stops

with CSS:

background: linear-gradient(to right,
     red 20%, orange 20% 40%, yellow 40% 60%, green 60% 80%, blue 80%);

  height: 300,
  width: 300,
  decoration: BoxDecoration(
    gradient: linearGradient(Alignment.centerRight, 
      ['red 20%', 'orange 20% 40%', 'yellow 40% 60%', 'green 60% 80%', 'blue 80%']),
  ),
);

*Note: The first argument can be Alignment as well as angle.
