Snackbar Material 3 theme overlay

See original GitHub issue

Description: I am following the Material 2 doc for Snackbar. However it does not apply with Material 3, how can we style Snackbar in Material 3 because currently none of the specified value color gets applied.

Source code:

<!-- Snackbar style on both light and night mode -->
    <style name="AppSnackbar" parent="Widget.Material3.Snackbar">
        <item name="materialThemeOverlay">@style/ThemeOverlay.App.Snackbar</item>
        <item name="actionTextColorAlpha">1</item>
    </style>

    <style name="Widget.App.SnackbarButton" parent="Widget.Material3.Button.TextButton.Snackbar">
        <item name="android:textColor">@color/colorPrimary_Accent</item>
    </style>

    <style name="ThemeOverlay.App.Snackbar" parent="">
        <!-- Text color -->
        <item name="colorPrimary">@color/colorPrimary_Accent</item>
        <!-- Background color -->
        <item name="colorSurface">@color/colorWhite_Primary</item>
        <item name="colorOnSurface">@color/colorWhite_Primary</item>
    </style>

Usage <item name="snackbarStyle">@style/AppSnackbar</item>

Actually you can. But the color attribute you need to override is ?attr/colorSurfaceInverse. : )

Hi @ArcherEmiya05, this is the source code for the layout used by Snackbar.

Instead of snackbarStyle, can you try using snackbarTextViewStyle (extend from Widget.Material3.Snackbar.TextView) and snackbarButtonStyle (extend from Widget.Material3.Button.TextButton.Snackbar) in your theme?

I think that should work and give you full flexibility for text colors and other attributes for the message / action button, but feel free to reopen if you’re still having issues.
