Buttons are very hard to read. I've added disabled buttons in a theme of the opposite mode for comparison.

In dark mode the button even disappears

Thank you. To summarize: the proposed solution would be to invert the background color of the Snackbar, which would be a breaking change.

For reference: Material Design 3 specs the colors as inverted. I believe, if we follow spec, the solution would be to invert the colors of disabled state inside of the snackbar as to align them with the inverted background.

@danilo-leal @Janpot to put this in context:

We have observed a conflict between the snackbar background color and the button's disabled state, particularly when the theme is in dark mode.

In light mode:

• Snackbar background color: rgb(50, 50, 50) (a dark color)
• Disabled button text color: rgba(0, 0, 0, 0.26) (a transparent dark color)

In dark mode:

• Snackbar background color: rgb(250, 250, 250) (a light color)
• Disabled button text color: rgba(255, 255, 255, 0.3) (a light color)

Currently, the button is using a more generic theme configuration styling, which is palette.action.disabled. We believe the issue could be resolved by reversing the snackbar background color, using a light color in light mode and a dark color in dark mode. However, we acknowledge that this change might be considered a breaking change.

We would like to seek your input on the best way to address this issue. Should we proceed with reversing the snackbar background color, potentially as a breaking change, or do you have alternative suggestions for resolving the conflict?
