Use case

I'm new to Flutter and I'm trying to configure a custom color scheme while respecting Material 3 color conventions. According to the Material 3 documentation, a tonal palette consists of thirteen tones, including white and black. A tone value of 100 represents maximum lightness and results in white. Each tone value between 0 and 100 expresses the amount of light present in the color.

I'm attempting to use the MaterialColor class to implement my custom colors, but it seems to be following the Material 2 convention instead.

I have referred to the Material 3 documentation (https://m3.material.io/styles/color/the-color-system/key-colors-tones#6bdb9471-b70d-42c9-8ace-76743c1fff13) and noticed that the color system and conventions described there differ from what I'm experiencing with the MaterialColor class.

Here are some screenshots illustrating the differences:

Proposal

Maybe an update to that class to support new Material 3 colors conventions?
