What's the difference between this two approaches? And why first is preferable?

@Composable
fun TestScreen(viewModel: TestViewModel = hiltViewModel()) {
    //content
}

@Composable
fun TestScreen() {
    val viewModel: TestViewModel = hiltViewModel()
    //content
}

Using hilt, you can easily mock the view model in both cases. But the first one allows you to pass in a ViewModel without having to setup hilt at all, so you would usually go with that one

The top option has it's viewModel "dependency" injected (passed through constructor) so it's typically easier to swap it out for testing.
