How Do I Add A Blur Effect At The Right Edge Horizontal Listview To Show That There Is More Content

I would like a way for the user to see that they can scroll horizontally on my horizontal ListView Thanks in advance Edit: Here is my code @wcyankees424 Container( height: 50,

Solution 1:

You can use ShaderMask with a gradient.

You can adjust inside the LinearGradient the stops and the colors to change the effect.

Maybe change Colors.white to Colors.trasnparent

Please try this code, to see some effect.

Widgetbuild(BuildContext context) {
    returnScaffold(
      body: Center(
        child: ShaderMask(
          shaderCallback: (Rect bounds) {
            return LinearGradient(
              colors: [Colors.white, Colors.white.withOpacity(0.05)],
              stops: [0.7, 1],
              tileMode: TileMode.mirror,
            ).createShader(bounds);
          },
          child: Container(
            height: 100,
            child: ListView(
              scrollDirection: Axis.horizontal,
              children: <Widget>[
                Card(
                  color: Colors.red,
                  child: Center(child: Text("012345678910 - 0123")),
                ),
                Card(
                  color: Colors.yellow,
                  child: Center(child: Text("012345678910 - 0123")),
                ),
                Card(
                  color: Colors.blue,
                  child: Center(child: Text("012345678910 - 0123")),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }

Solution 2:

Is this the effect you wanted? Try this out let me know what you think.

Positioned(
            top: 0,
            right: 0,
            width: 50,
            height: MediaQuery.of(context).size.height,
            child: ClipRRect(
              child: BackdropFilter(
                filter: ImageFilter.blur(sigmaX: 2.5, sigmaY: 2.5), //this determines the blur in the x and y directions best to keep to relitivly low numberschild: Container(
                  decoration: BoxDecoration(
                    gradient: LinearGradient(
                      colors: [
                        Colors.black.withOpacity(0),
                        Colors.black.withOpacity(
                            0.3), //This controls the darkness of the bar
                      ],
                      // stops: [0, 1], if you want to adjust the gradiet this is where you would do it
                    ),
                  ),
                ),
              ),
            ),
          ),
