Review Jetpack compose codes - theme

To set Theme

@Composable
fun BasicCodelabTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    dynamicColor: Boolean = true,
    content: @Composable () -> Unit
) {
    val colorScheme = when {
        dynamicColor && Build.VERSION.SDK_INT >= Build.VERSION_CODES.S -> {
            val context = LocalContext.current
            if (darkTheme) dynamicDarkColorScheme(context) 
            else dynamicLightColorScheme(context)
        }
        darkTheme -> DarkColorScheme
        else -> LightColorScheme
    }
    val view = LocalView.current
    if (!view.isInEditMode) {
        SideEffect {
            (view.context as Activity).window.statusBarColor = colorScheme.primary.toArgb()
            ViewCompat.getWindowInsetsController(view)?.isAppearanceLightStatusBars = darkTheme
        }
    }

    MaterialTheme(
        colorScheme = colorScheme,
        typography = Typography,
        content = content
    )
}

• DarkColorScheme and LightColorScheme define color schemes for dark and light themes respectively.
• The BasicCodelabTheme function sets the application’s theme, taking darkTheme and dynamicColor parameters.
• SideEffect is used to set the status bar color of the activity when the view is not in edit mode, and adjust the system status bar theme.
• MaterialTheme wraps actual UI content, applying the configured color scheme and typography.

class MainActivity : ComponentActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        enableEdgeToEdge()
        setContent {
            BasicCodelabTheme {
                MyApp(modifier = Modifier.fillMaxSize())
            }
        }
    }
}
