How to implement guide with dynamic theme switching in jetpack compose for android 14
After trying multiple solutions online, I still can't figure this out. I'm dealing with I'm working through a tutorial and Quick question that's been bugging me - After trying multiple solutions online, I still can't figure this out... I’m experiencing a question with dynamically switching themes in my Jetpack Compose application targeting Android 14. I have two themes: `LightTheme` and `DarkTheme`, and I want to toggle between them based on user preference. However, when I switch themes, the UI does not update as expected, and I see a flicker before the new theme is applied. Here’s a simplified version of my code: ```kotlin @Composable fun MyApp(isDarkTheme: Boolean) { MaterialTheme(colors = if (isDarkTheme) DarkThemeColors else LightThemeColors) { // Your main UI here MainScreen() } } @Composable fun MainScreen() { // UI elements that should react to theme changes Text("Hello World") } @Composable fun ThemeToggleButton(onToggle: () -> Unit) { Button(onClick = onToggle) { Text("Toggle Theme") } } ``` In my `MainActivity`, I manage the theme state using a `ViewModel`: ```kotlin class MainViewModel : ViewModel() { var isDarkTheme by mutableStateOf(false) private set fun toggleTheme() { isDarkTheme = !isDarkTheme } } ``` Whenever I call `toggleTheme()`, the `MyApp` composable is recomposed, but the UI doesn’t update smoothly. Instead, there’s a noticeable delay and flicker. I’ve tried using `remember` to store the theme state, but that didn’t seem to help either. Is there something specific I’m missing in how I’m managing state or applying themes in Jetpack Compose? Any insights would be appreciated! Any ideas what could be causing this? For context: I'm using Kotlin on Linux. Am I missing something obvious? Any advice would be much appreciated. I'm using Kotlin latest in this project. Thanks for any help you can provide!
