Material theme builder version 20, released in May 2024, is not operational. The plugin generates theme colours but does not update them in any project files other than the original kit project. This means that if you had any work using Material 3 kit, you are not able to update the theme since May 2024. It is not possible to do any theme-related M3 work with a custom theme since May 2024. Themes in any project that people had done in Material3 UI Kit cannot be updated anymore since May 2024.
There is no other Material theme builder plugin. We are hostages of the situation.
There are tens, if not hundreds, of reports on the M3 DK page and on the Theme Builder itself page where it has been ignored since early 2024.
It appears that version 20 of the plugin was released untested, and the development team was immediately reassigned or disbanded. Nobody from the Material team reads bug reports; nobody responds.
Figma announced the category of UI kits but did nothing else; nobody tests anything that is in the plugin store. The provider uploaded a broken plugin that prevents people from working. Figma allowed this to happen. You have the resources, billions of dollars; couldn’t you assign a developer to fix the M3 Theme builder plugin?
And cue the answer “we will pass your feedback for consideration.” It is a disaster! It is not “feedback for consideration”.
