Decompile .class file ,bytecode version :52.0 (java 8)

Question

I encountered an issue while learning Jetpack Compose, which resulted in my Compose class appearing as shown in the image. Despite my efforts, I haven't been able to resolve this issue, and I suspect it may be related to the decompilation process of Java 8.

.class file instead of jet-pack compose class

// IntelliJ API Decompiler stub source generated from a class file
// Implementation of methods is not available

package androidx.compose.material3

private val FabSpacing: androidx.compose.ui.unit.Dp /* compiled code */

internal val LocalFabPlacement: androidx.compose.runtime.ProvidableCompositionLocal<androidx.compose.material3.FabPlacement?> /* compiled code */

@androidx.compose.material3.ExperimentalMaterial3Api public var ScaffoldSubcomposeInMeasureFix: kotlin.Boolean /* compiled code */
    public final @androidx.compose.material3.ExperimentalMaterial3Api get
    public final @androidx.compose.material3.ExperimentalMaterial3Api set(value: kotlin.Boolean) {/* compiled code */ }

I attempted to download the source of the decompiled file and installed the Kotlin to Java decompile plug-in, but unfortunately, these actions did not help me solve the problem . Can anyone provide guidance on how to address this issue effectively?

when i press on Donwload resources , i got this wrong
