rememberPagerState() forcing overload error due to mismatch between Compose Foundation versions in androidMain and commonMain

[cryptrr]

Describe the bug

Using 'rememberPagerState(Int = ..., Float = ...): PagerState' is an error. Please use the overload where you can provide a source of truth for the pageCount.

I'm using the official compose multiplatform template. From here

androidMain is using foundation 1.5.0-beta01 while commonMain is using 1.4.0

old overloads of rememberPagerState has been force disabled in Foundation 1.5.0-beta with the above error.

So it is impossible to use Pagers in commonMain code because the latest version of foundation available for multiplatform is 1.4.0 and does not have the overloads necessary to compile.

So how to downgrade foundation in androidMain since i'm not seeing this gradle dependency in the val androidMain by getting {} block.

Or do I need to copy all the code from foundation 1.5.0-beta?

Affected platforms Select one of the platforms below:

• All

Versions

• Kotlin version*: 1.8.20
• Compose Multiplatform version*: 1.4.0

To Reproduce Steps and/or the code snippet to reproduce the behavior:

1. Go to https://github.com/JetBrains/compose-multiplatform-ios-android-template and clone
2. Use VerticalPager or HorizontalPager with rememberPagerState()
3. See error Using 'rememberPagerState(Int = ..., Float = ...): PagerState' is an error. Please use the overload where you can provide a source of truth for the pageCount.

Expected behavior The foundation versions should be same or there should be a better way to downgrade

[cryptrr]

This error happens during compile time hence the compose compiler must be checking for every usage of rememberPagerState(). So I guess the compose compiler should also be downgraded to prevent this error.

How did you get 1.5.0-beta for foundation in androidMain?

I added this snipped to inside the Column in App.kt (in commonMain) and it works perfectly for me:

            val pagerState = rememberPagerState()
            HorizontalPager(
                pageCount = 10,
                modifier = Modifier.fillMaxWidth().padding(top = 32.dp),
                state = pagerState
            ){
                Text(
                    text = "Page $it",
                    textAlign = TextAlign.Center,
                    modifier = Modifier.fillMaxWidth().background(Color.LightGray).padding(40.dp)
                )
            }

I have no idea :/ This is my androidMain dependencies list

val androidMain by getting {
            dependencies {
                api("androidx.activity:activity-compose:1.7.2")
                implementation("androidx.media3:media3-exoplayer:1.0.2")
                implementation("androidx.media3:media3-ui:1.0.2")
                implementation("androidx.constraintlayout:constraintlayout-compose:1.1.0-alpha10")
                api("androidx.appcompat:appcompat:1.6.1")
                api("androidx.core:core-ktx:1.10.1")
                implementation ("com.github.skydoves:cloudy:0.1.2")
                implementation("org.jetbrains.kotlinx:kotlinx-serialization-json:1.5.1")
                implementation("com.google.accompanist:accompanist-systemuicontroller:0.31.3-beta")
            }
        }

and I'm using the default imports for commonMain

 val commonMain by getting {
            dependencies {

                implementation(compose.runtime)
                implementation(compose.foundation)
                implementation(compose.material3)
                implementation(compose.material)
                implementation(compose.materialIconsExtended)
                @OptIn(org.jetbrains.compose.ExperimentalComposeLibrary::class)
                implementation(compose.components.resources)
               ....
}

Still I have foundation 1.5.0-beta in androidMain and 1.4.0 in commonMain

[cryptrr]

All of these dependencies are somehow using 1.5.0-beta in androidMain

It's got to do with some third party libraries bumping it up.

You can run the gradle dependencies task from inside androidApp to see the tree of dependencies. In your case, compose 1.5.0-beta01 is pulled in by

• androidx.constraintlayout:constraintlayout-compose:1.1.0-alpha10
• com.github.skydoves:cloudy:0.1.2
• com.google.accompanist:accompanist-systemuicontroller:0.31.3-beta

[cryptrr]

Thanks. Is downgrading these dependencies the only way to fix this problem?

[cryptrr]

I checked the dependency tree. Weirdly it says even material3:1.0.1 is depending upon foundation 1.5.0-beta1

[cryptrr]

Removing accompanist and constraintlayout removed foundation 1.5.0 . Thanks.

[cryptrr]

Downgrading accompanist to v0.30.1 uses compose 1.4.0 and fixes this.
