Showing the default preference setting in split second on time while start the app #13

In the ViewModel there's code ,

data class DessertReleaseUiState( val isLinearLayout: Boolean = true, val toggleContentDescription: Int = if (isLinearLayout) R.string.grid_layout_toggle else R.string.linear_layout_toggle, val toggleIcon: Int = if (isLinearLayout) R.drawable.ic_grid_layout else R.drawable.ic_linear_layout )

which shows the default settings, after in very short delay the preference setting restored. I think it would be nice to showing any splash screen or some loading animation in the meantime that moment of time

I've noticed this too. When you change the layout to grid and the preference is stored, when relaunching the app it will display the linear layout for a split second before switching to grid (it may not be visible in release configuration but I am not sure).

I am not sure of the exact cause of this but I think it occurs when we convert our cold flow to a hot one in the viewmodel, it could have something to do with the initialValue parameter.

I also noticed it. It is because of DataStore feature, which supports fully asynchronous work, not synchronous.
