Is it planned to provide a style ambient for each material component?

E.g. a ButtonStyleAmbient to change the default style of all buttons.

Because it looks like code can get a bit messy if there will be no way for global theming.

[Adam Powell]

No. The existence of this in the current style and theme XML system is a regret that caused a lot of abstraction problems.

[Adam Powell]

The material theming is limited to globally applicable properties like colors and shapes that are more universal across components, not targeting specific components from outside

[Manuel Wrage]

So what's the recommended way to achieve consistent theming troughout parts of the ui?

My guess is we have to create something like @Composable fun MyThemedButton()

[Adam Powell]

The color, shape and typography theming will get you quite far. The problem with theme settings for specific widgets is that it becomes more inconsistent in a hurry. It's easier to theme things consistently without them 🙂

[Adam Powell]

And yes, you can also always write your own composables that express your own style and use those consistently in a part of your UI

[Adam Powell]

Coming back to this with a real keyboard rather than phone keyboard - the problem that things like android:attr/defaultButtonStyle created is that it targets implementation details of composite widgets rather than a generally applicable api

[Adam Powell]

it made composite widgets fairly difficult to create with views while maintaining expectations that this sort of thing would work. See the Android date and time pickers over the years for a good example

[Adam Powell]

Whether a composite date picker uses a raised or outlined button for a confirm button is an implementation detail of the picker and not necessarily something that the embedding app should be able to theme out from under the picker (unless the picker exposes an API for it)

I understand your points thanks for your response.
