Download

If the gradle cannot build the project because of this library, update your settings.gradle file with

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.PREFER_PROJECT)
    repositories {
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
        maven { url 'https://jitpack.io' }
    }
}

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Add it in your app build.gradle:

dependencies {
    implementation "com.github.aakarshrestha:compose-pager-snap-helper:[version]"
}

        width = 320.dp, //required
        content = { listState -> //this param is provided by the method itself, add this param below.
            LazyRow(
                state = listState, //add listState param
            ) {
                items(count = count) { item ->
                    Card(
                        modifier = Modifier
                            .width(width)
                            .height(350.dp)
                            .padding(
                                start = if (item == 0) 16.dp else 16.dp,
                                top = 16.dp, bottom = 16.dp,
                                end = if (item == 4) 16.dp else 8.dp),
                        backgroundColor = Color.LightGray, shape = RoundedCornerShape(12)
                    ) {
                        //Put text or whatever here

                    }
                }
            }
        }
    )
