Describe the bug

On Samsung Galaxy Tab S10+ 5G (Android 15, One UI 7.0), the "Start" button in the Amplify Liveness SDK is hidden by the taskbar overlay at the bottom of the screen. This prevents users from starting the liveness check. The issue does not occur with other SDKs such as Onfido, which correctly handle overlays and safe areas.

Reproduction steps (if applicable)

• Integrate Amplify Liveness SDK in a Flutter app (using the official plugin).
• Run the app on Samsung Galaxy Tab S10+ 5G (Android 15, One UI 7.0).
• Navigate to the liveness check screen.
• Observe that the "Start" button is hidden by the taskbar overlay.

Code Snippet

// Put your code below this line.

// Relevant code from FaceLivenessView.kt

internal class FaceLivenessView(
    context: Context,
    id: Int,
    creationParams: Map<String?, Any?>?,
    val handler: EventStreamHandler
) : PlatformView {
    // ...existing code...

    init {
        composeView.setContent {
            // ...existing code...

            FaceLivenessDetector(
                sessionId = sessionId,
                disableStartView = disableStartView,
                region = region,
                onComplete = { handler.onComplete() },
                onError = { error ->
                    // ...error handling...
                }
            )
        }
    }
}

This class is responsible for rendering the Amplify Liveness UI in the Flutter plugin. The FaceLivenessDetector is initialized with parameters from Flutter, including disableStartView, which controls the visibility of the start screen. The issue occurs when the "Start" button is hidden by the taskbar overlay on certain Samsung devices.

Additional information and screenshots

Device Model: Samsung Galaxy Tab S10+ 5G
Android Version: 15
One UI Version: 7.0

The "Start" button is hidden by the taskbar overlay at the bottom of the screen.
This affects usability, as users cannot proceed with the liveness check.

This is not a bug within the component. The FaceLivenessDetector is a standard Jetpack Compose composable. It will use whatever size you give it. You should wrap it in a Box/Column/Row, etc and set proper margins/padding on the outer container.
