Hi! Thanks for this awesome package.

I was trying to create the same result like the outer wave example:

In the available example there is also no such version. Can you please provide an example of this?

Thanks!

Explain the details for making this change. What existing problem does the pull request solve?

With the WaveWidget inside a StreamBuilder it wasn't possible to change the waveAmplitude value based on new stream data. This change allows you to update the waveAmplitude value and have it reflected in the waves that are displayed.

This may not be the best way to achieve this behavior, but if it's useful then great!

Temporary fix for the following errors:

wave-0.1.0/lib/config.dart:46:13: Error: Method not found: 'throwNullError'.
            throwNullError('custom', 'colors` or `gradients');

Describe the bug in the hosting simple example page with just the wave plugin as background take 1 minute and 3 seconds loading.

To Reproduce just host a Flutter web project with this build

@override
 Widget build(BuildContext context) {
   return Scaffold(
     body: Center(
       child: WaveWidget(
         config: CustomConfig(
           gradients: [
             [Colors.red, Color(0xEEF44336)],
             [Colors.red[800], Color(0x77E57373)],
             [Colors.orange, Color(0x66FF9800)],
             [Colors.yellow, Color(0x55FFEB3B)]
           ],
           durations: [35000, 19440, 10800, 6000],
           heightPercentages: [0.20, 0.23, 0.25, 0.30],
           blur: MaskFilter.blur(BlurStyle.solid, 0.0),
           gradientBegin: Alignment.bottomLeft,
           gradientEnd: Alignment.topRight,
         ),
         backgroundColor: Colors.transparent,
         size: Size(double.infinity, double.infinity),
         waveAmplitude: 0,
       ),
     ),
   );
 }

Expected behavior A nice loading time

please add ability to add background image in your amazing plugin some help for you (^_-), wave.dart Line(330)

return Container(
      color: widget.backgroundColor,
      child: Stack(
        children: _buildPaints(),

Using the git example https://github.com/glorylab/wave, I am trying to flip the widget. either by flipping the card

Transform(
  transform: Matrix4.rotationY(math.pi),
  child: _buildCard(

or by flipping the control

Card(
...
  child: Transform(
    transform: Matrix4.rotationY(math.pi),
    child: WaveWidget(
      config: config,
      backgroundColor: backgroundColor,
      backgroundImage: backgroundImage,
      size: Size(double.infinity, double.infinity),
      waveAmplitude: 0,
    ),
),

Both methods fail - first method completely hides the card, the second method shows empty card.

Can you please check this?

Thank you!

I try many ways for create waves with height full screen but no way found this is output

and this is my code

return Stack( children: <Widget>[ Align( alignment: Alignment.bottomCenter, child: WaveWidget( config: CustomConfig( gradients: [....], durations: [19440, 10800, 6000], heightPercentages: [0.05, 0.01, 0.02], blur: MaskFilter.blur(BlurStyle.solid, 10), gradientBegin: Alignment.bottomCenter, gradientEnd: Alignment.topCenter, ), backgroundColor: Color.fromARGB(255, 22, 21, 21), size: Size( double.infinity, MediaQuery.of(context).size.height, ), waveAmplitude: 14, ), ),

Is your feature request related to a problem? Please describe. This suggested feature would enable customization on the wave animation cycle.

Describe the solution you'd like An enum for every possible action on AnimationStatus.completed, and an additional parameter to set the animation's Curve.

Describe alternatives you've considered Add a 'curve' parameter in WaveWidget, 'reverseOnEnd' and 'resetOnEnd'.

Additional context I've made a fork and a commit at AlvBarros/wave, and was about to create a Pull Request to this plugin. It's not the best solution, but solved my problem and I thought that I'd share.

With the WaveWidget inside a StreamBuilder it wasn't possible to change the waveAmplitude value based on new stream data. This change allows you to update the waveAmplitude value and have it reflected in the waves that are displayed.

This may not be the best way to achieve this behavior, but if it's useful then great!

I also haven't migrated to null safety in my own project, so I don't know the implications of what I have done here, other than that it builds without errors.
