Is glance supported?

Question

Hey there!

Sorry for the potentially dumb question: I'm working on building out a glance widget (that will actually be offered via a Flutter app) and I was hoping to use this library to do that. I think what I'm discovering (I have not worked with native Android since just before compose was introduced) is that the glance and compose libraries are somewhat fragmented. For instance when trying to build a Composable containing a chart for the widget I am seeing the following:

java.lang.IllegalStateException: CompositionLocal LocalContext not present

	at androidx.compose.ui.platform.AndroidCompositionLocals_androidKt.access$noLocalProvidedFor(AndroidCompositionLocals.android.kt:1)

	at com.patrykandpatrick.vico.compose.cartesian.CartesianChartHostKt.CartesianChartHost(CartesianChartHost.kt:176)

My reading on this is that the use of compose's LocalContext.current by vico is not compatible with a glance Composable; is that correct? If all the above is correct, am I correct in saying I cannot use vico with glance? Thanks again for entertaining my potentially dumb question!

Vico version(s)

2.0.0-alpha.22

UI framework(s)

Jetpack Compose

Hello! No worries about the question—we’re happy to help.

As noted here, Glance uses only some foundational Jetpack Compose APIs, and the two frameworks generally aren’t interoperable. Thus, Vico can’t be used with Glance, I’m afraid. This applies to most high-level Jetpack Compose libraries.

Thanks for the answer! I appreciate it. Unfortunate answer but I totally understand, thank you!
