How to override the text color in TextField in Jetpack Compose using MaterialTheme?

Issue

I'm trying to use TextField() from Jetpack Compose. I want the text color to be white.

I found this to be working:

ProvideTextStyle(TextStyle(color = Color.White)) {
   TextField(
       ...
   )
}

However, I want to override this in the Theme level, so that I don't need to repeatedly write ProvideTextStyle. I saw that MaterialTheme only accepts the following params:

@Composable
fun MaterialTheme(
    colors: Colors = MaterialTheme.colors,
    typography: Typography = MaterialTheme.typography,
    shapes: Shapes = MaterialTheme.shapes,
    content: @Composable () -> Unit
)

So I'm not sure how to do it. Can someone help?

(compose version = 1.0.0-alpha11)

Solution

I want to override this in the Theme level

Modify the content of MaterialTheme composable in your app's theme composable to include TextStyle.

@Composable
fun MyAppTheme(
    darkTheme: Boolean = isSystemInDarkTheme(),
    content: @Composable() () -> Unit
) {
    val colors = if (darkTheme) {
        DarkColorPalette
    } else {
        LightColorPalette
    }

    MaterialTheme(
        colors = colors,
        typography = Typography,
        shapes = Shapes,
        content = {
            ProvideTextStyle(
                value = TextStyle(color = Color.White),
                content = content
            )
        }
    )
}

Now your provided TextStyle will be used at App theme level.

setContent {
    MyAppTheme {
        // app content
    }
}
