How to create a linear gradient with 45 degrees in Flutter?

Related searches

I can not understand how to operate in degrees LinearGradient. I have the following code:

Container(
        height: 100.0,
        decoration: BoxDecoration(
          borderRadius: BorderRadius.circular(6.0),
          gradient: LinearGradient(begin: FractionalOffset.topLeft, end: FractionalOffset.bottomRight, colors: [
            Color(0xFF148535),
            Color(0xFF148535),
            Color(0XFF0D6630),
            Color(0XFF0D6630),
            Color(0xFF148535),
            Color(0xFF148535),
          ], stops: [
            0.0,
            0.3,
            0.3,
            0.7,
            0.7,
            1.0
          ]),
        ),
      );

But .topLeft and '.bottomRight' don't do that is required. Picture that is below shows what I want to get. (The picture has a offset and it doesn't fit to [0.0, 0.3, 0.3, 0.7, 0.7, 1.0] because this is just example)

Try using these values:

 LinearGradient(
          begin: Alignment(-1.0, -2.0),
          end: Alignment(1.0, 2.0),

Or event better

   LinearGradient(
          begin: Alignment(-1.0, -4.0),
          end: Alignment(1.0, 4.0),

Y: parameter description

The distance fraction in the vertical direction. A value of -1.0 corresponds to the topmost edge. A value of 1.0 corresponds to the bottommost edge. Values are not limited to that range; /// values less than -1.0 represent positions above the top, and values /// greater than 1.0 represent positions below the bottom.

Gradients in Flutter…. Gradient, a reflection of your…, In this article, I have made use of gradients available from the flutter framework. of flutter, which comprises of two type of gradients — Linear Gradient and Radial Gradient… flutter_programs - Samples for flutter programs etc. about this great technology to teach you how to build beautiful apps with it. Good. From now, we can actually start creating our gradient. In Flutter, there are three types of gradients, a linear gradient, a radial gradient and a sweep gradient. In this post, we’ll be exploring all three. Creating a LinearGradient. First of all, let’s implement a linear gradient into our application:

Use Alignment.topLeft and Alignment.bottomRight

LinearGradient(
      colors: [Colors.cyanAccent, Colors.amberAccent],
      begin: Alignment.topLeft,
      end: Alignment.bottomRight,
      tileMode: TileMode.clamp),

SweepGradient class - painting library - Dart API, To use a SweepGradient to paint on a canvas directly, see createShader. link This sample takes the above gradient and rotates it by math.pi/4 radians, i.e. 45 degrees. LinearGradient, which displays a gradient in parallel lines, and has an TileMode.clamp, GradientTransform transform}): Creates a sweep gradient. []. Gradient is coming back as a trend in UI design, I once have to create a button with a gradient background. Thanks to Flutter, everything seems to be easy with built-in Gradient. Unlike React Native, where you have to lean on 3rd party library. In this article, I will show you how to create a Gradient background button using Flutter a Cross

If you want to use gradient by angles, It's better to use SweepGradient. You can play with center, startAngle, and endAngle. Here is the solution something that you are looking for:

BoxDecoration(
        gradient: SweepGradient(
          center: AlignmentDirectional(1, -1),
          startAngle: 1.7,
          endAngle: 3
          ,
          colors: const <Color>[
            Color(0xFF148535),
            Color(0xFF148535),
            Color(0XFF0D6630),
            Color(0XFF0D6630),
            Color(0xFF148535),
            Color(0xFF148535),              ],
          stops: const <double>[0.0,0.3,0.3,0.7,0.7,1.0]),),

Here is a very simple example for everyone else who wants to understand and play with Gradient and Angles:

 Container(
      height: 400,
      decoration: BoxDecoration(
        gradient: SweepGradient(
          center: FractionalOffset.topRight,
          startAngle: 2,
          endAngle: 5
          ,
          colors: const <Color>[
            Colors.red, // blue
            Colors.blue 
          ],
          stops: const <double>[0.0, 0.5],
        ),
      ),
    ),
