Question

I’m following official docs to create a simple Jetpack Glance widget. I tried previewing the UI but I’m failing to do so. A portion of my code:

package io.github.yamin8000.owl.ui.content.widget

import android.content.Context
import androidx.compose.runtime.Composable
import androidx.compose.ui.tooling.preview.Preview
import androidx.glance.GlanceId
import androidx.glance.GlanceTheme
import androidx.glance.appwidget.GlanceAppWidget
import androidx.glance.appwidget.provideContent
import androidx.glance.text.Text

internal class Widget : GlanceAppWidget() {
    override suspend fun provideGlance(context: Context, id: GlanceId) {
        provideContent {
            GlanceTheme {
                WidgetContent()
            }
        }
    }

    @Preview(showBackground = true, showSystemUi = true)
    @Composable
    fun WidgetContent() {
        Text("Some Text!")
    }
}

Failed to instantiate Composition Local
This preview was unable to find a CompositionLocal. You might need to define it so it can render correctly.
And this is the stack trace I’m receiving: (Widget.kt:45 is Text("Some Text!"))

This is my current enviroment

Android Studio Jellyfish | 2023.3.1 Patch 1
Build #AI-233.14808.21.2331.11842104, built on May 15, 2024
Runtime version: 17.0.10+0--11572160 amd64

Some questions like this suggest adding androidx.compose.ui:ui-tooling library which is irrelevant for me because it’s already added and other previews outside of Glance are working just fine.
