When using Preview, it is cumbersome to set the Theme every time.

@Composable
@Preview
private fun SamplePreview() {
    MyTheme {
        Sample()
    }
}

It would be great if we could create a custom preview annotation to omit the theme setting, as shown below:

@Preview(themeProvider = MyThemeProvider::class)
annotation class PreviewMyTheme

@Composable
@PreviewMyTheme
private fun SamplePreview() {
    Sample()
}

Specifically, having an interface like the following would be beneficial:

class MyThemeProvider : ThemeProvider {
    @Composable
    override fun Theme(content: @Composable () -> Unit) {
        MyTheme {
            content()
        }
    }
}

interface ThemeProvider {
    @Composable
    fun Theme(content: @Composable () -> Unit)
}
