动画渐变

Animate Gradient

This Package lets you make animated gradients without any hassle. Just pass the primary and secondary colors and you're done. You can do amazing effects using the alignments. For More info read the docs below.

Usage

Create your first animated gradient.

The only two required arguments are the primaryColors and secondaryColors.

| primaryColors length must greater or equal to 2.| | secondaryColors length must be equal to primaryColors length.|

    import 'package:animate_gradient/animate_gradient.dart';

     AnimateGradient(
        primaryColors: const [
          Colors.pink,
          Colors.pinkAccent,
          Colors.white,
        ],
        secondaryColors: const [
          Colors.blue,
          Colors.blueAccent,
          Colors.white,
        ],
        child: YourWidget(),
      ),

Play with alignments.

Alignments are optional. You can pass any of the following alignments.

primaryBegin primaryEnd secondaryBegin secondaryEnd

With this in place, you can have some crazy effects.

   import 'package:animate_gradient/animate_gradient.dart';

    AnimateGradient(
       primaryBegin: Alignment.topLeft,
       primaryEnd: Alignment.bottomLeft,
       secondaryBegin: Alignment.bottomLeft,
       secondaryEnd: Alignment.topRight,
       primaryColors: const [
         Colors.pink,
         Colors.pinkAccent,
         Colors.white,
       ],
       secondaryColors: const [
         Colors.white,
         Colors.blueAccent,
         Colors.blue,
       ],
       child: YourWidget(),
     ),

Alternatively! Use AlignemntGeometry for better control

With the apps built in rtl format normal Alignments cannot always work. So, you can use AlignemntGeometry instead.

primaryBegin --> primaryBeginGeometry

primaryEnd --> primaryEndGeometry

secondaryBegin --> secondaryBeginGeometry

secondaryEnd --> secondaryEndGeometry

With this, you also have an additional property textDirectionForGeometry. This will be used to resolve the AlignmentGeometry

   import 'package:animate_gradient/animate_gradient.dart';

    AnimateGradient(
      primaryBeginGeometry: const AlignmentDirectional(0, 1),
      primaryEndGeometry: const AlignmentDirectional(0, 2),
      secondaryBeginGeometry: const AlignmentDirectional(2, 0),
      secondaryEndGeometry: const AlignmentDirectional(0, -0.8),
      textDirectionForGeometry: TextDirection.rtl,
       primaryColors: const [
         Colors.pink,
         Colors.pinkAccent,
         Colors.white,
       ],
       secondaryColors: const [
         Colors.white,
         Colors.blueAccent,
         Colors.blue,
       ],
       child: YourWidget(),
     ),

Please note that AlignmentGeometry will be given more priority over Alignment
