OsmCompose

🚧⛔ This is an exercise to familiarise myself with Compose and

Compose-style APIs, it's incomplete (and will remain so) and untested

Do NOT use this for anything 🚧⛔️

Description

osmdroid's MapView as Jetpack Compose composable with Compose-style APIs for creating markers, polylines and such.

here's what the API looks like:

OsmMap(
    modifier = Modifier
        .fillMaxWidth()
        .weight(9f)
        .clip(
            RoundedCornerShape(topStart = 16.dp, topEnd = 16.dp)
        ),
    mapControllerState = controllerState
) {
    Marker(
        state = rememberMarkerState(
            position = GeoPoint(
                35.69555,
                51.37833
            )
        ),
        icon = ContextCompat.getDrawable(
            this@MainActivity,
            R.drawable.baseline_push_pin_24
        ),
        onClick = { _, _ -> clicked = !clicked; true })
    Polyline(
        state = rememberPolylineState(
            points = listOf(
                GeoPoint(
                    35.69555,

        }
    )

    )
