inlay_compose

Jetpack Compose integration for the inlay add-to-app framework. Embed inlay Flutter screens and dialogs directly in Compose UIs with typed results.

This is a separate package so that projects not using Compose depend only on inlay - the core plugin pulls in no Compose transitive dependencies. Android-only.

Setup

Add it next to inlay in your Flutter module's pubspec.yaml:

dependencies:
  inlay: ^0.1.0
  inlay_compose: ^0.1.0

Embed a Flutter screen

InlayFlutterScreen renders an inlay Flutter page as a regular Compose destination:

import co.leancode.inlay.compose.InlayFlutterScreen

NavHost(navController, startDestination = "home") {
    composable("home") { HomeScreen() }

    composable("counter") {
        InlayFlutterScreen(
            route = CounterPage(seed = null),
            modifier = Modifier.fillMaxSize(),
            onResult = { count ->
                // count: Long? - already decoded
            },
        )
    }
}

When Flutter calls pop(), the screen integrates with Compose Navigation's back stack via onBackPressedDispatcher. onResult is invoked exactly once - with the result the page pops with, or null when the destination leaves the composition without one.

Show a Flutter dialog

InlayFlutterDialog is state-driven, the Compose counterpart of SwiftUI's .inlayDialog modifier. While isPresented is true, a transparent dialog window is shown over the Activity and Flutter renders the dialog content (barrier, animation, positioning):

import co.leancode.inlay.compose.InlayFlutterDialog

var showDialog by remember { mutableStateOf(false) }
var lastResult by remember { mutableStateOf<String?>(null) }

Button(onClick = { showDialog = true }) { Text("Delete") }

InlayFlutterDialog(
    isPresented = showDialog,
    route = ConfirmDeleteDialog(itemId = "42"),
    onDismissRequest = { showDialog = false },
    onResult = { confirmed ->
        lastResult = confirmed?.toString() // confirmed: Boolean? - already decoded
    },
)

Do not wrap InlayFlutterDialog in a Compose Dialog or a Compose Navigation dialog() destination - it manages its own window (and a FragmentManager cannot attach fragments inside a Compose dialog window). onDismissRequest fires when the dialog goes away for any reason (Flutter pop, barrier tap, back); flip isPresented back to false there.
