Crash

[T8RIN]

I have no idea, why this happens, maybe that's because i use newer compose version...

[galaxygoldfish]

What compose version are you using in that project?

[T8RIN]

Latest, 1.5.0-beta01 👀

[galaxygoldfish]

It looks like in the waveslider library we use the compose BOM package so you could try that. It was automatically created by Android Studio as version 2023.05.01 (see libs.versions.toml)

[T8RIN]

The thing that worked, is that I copied the module to the project, and bumped compose to 1.5.0-beta01, and had to downgrade minSdk to 21, have no idea, why 26 used here, cause compose needs 21 only
:(

[galaxygoldfish]

Oh so it doesn't crash when minSdk is 21?

[T8RIN]

No, I meant that there is no point in putting 26 if everything works with 21 👀

[T8RIN]

And with the latest compose version it also doesn't crash

[galaxygoldfish]

Merged PR updating mikSdk, and I found that the latest compose BOM is what is currently in the project so I changed it to individual dependencies, however while the compose version and material versions are updated to the latest one, it breaks the current implementation of the steps because they changed some values to be internal only that we were using to calculate the position of each tick :(

[T8RIN]

Yes! But i found solution, how to fix it 👀

[T8RIN]

Just copy private function, which creates step fractions, and that's it :)

[YounesBouhouche]

I found the solution !
In the update of androidx.compose.material3:material3-*:1.2.0-alpha08, they made sliderPositions depreacted and sliderPositions.tickFractions internal, so I copied the WaveSlider function then I replaced this :

sliderPositions.tickFractions.groupBy {
                    it > sliderPositions.activeRange.endInclusive ||
                            it < sliderPositions.activeRange.start
                }

with this :

stepsToTickFractions(sliderState.steps).groupBy {
                    it > sliderState.valueRange.endInclusive ||
                            it < sliderState.valueRange.start
                }

I found the solution !
In the update of androidx.compose.material3:material3-*:1.2.0-alpha08, they made sliderPositions depreacted and sliderPositions.tickFractions internal, so I copied the WaveSlider function then I replaced this :

sliderPositions.tickFractions.groupBy {
                    it > sliderPositions.activeRange.endInclusive ||
                            it < sliderPositions.activeRange.start
                }

with this :

stepsToTickFractions(sliderState.steps).groupBy {
                    it > sliderState.valueRange.endInclusive ||
                            it < sliderState.valueRange.start

Do you mean pull request ?
I know it's silly question but I'm new in Github

@YounesBouhouche did you noticed Layout Node not attached to owner exception after updating to 1.2.0-06 or 07-08 ?

I found the solution !
In the update of androidx.compose.material3:material3-*:1.2.0-alpha08, they made sliderPositions depreacted and sliderPositions.tickFractions internal, so I copied the WaveSlider function then I replaced this :

sliderPositions.tickFractions.groupBy {

                            it < sliderPositions.activeRange.start
                }

with this :

stepsToTickFractions(sliderState.steps).groupBy {
                    it > sliderState.valueRange.endInclusive ||

I hope the developer implement it as soon as possible

Wow, thanks for that, i'll be waiting too, maybe you can open PR?

Me too, but what's PR? how to open it?

You need to fork the project and then apply your changes in your fork, and then open pull request on GitHub

Hi all, got back to maintaining this project and I have updated WaveSlider.kt with the fix in this commit [cbab52b]

@T8RIN @YounesBouhouche Does this address the issue?
