There is a report about it in kotlinlang Slack: https://kotlinlang.slack.com/archives/C01D6HTPATV/p1706005056105739

Thanks for the report!

The release notes documentation has been edited to clarify this change in behavior for line height.

To support non-standard text sizes, we encourage users to follow the Material design system and use a different type scale rather than changing the font size directly. Alternatively, users can overwrite the line height like so: style = LocalTextStyle.current.copy(lineHeight = TextUnit.Unspecified), or create a custom Typography entirely.

In my case, I have multiple font sizes in the same Text (using SpanStyle in AnnotatedString). There are legitimate reasons for this. For example, when combining Chinese and English (phonetic) together (for language-learning purposes).

out of curiousity… if this isnt immediately planned, have you considered changing he default colors at all? a couple things i noticed:

(1) i could see the choice of purple + blue clashing with a number of existing apps, and maybe there are some better defaults that could be used to at least make the colors stand out less.

(2) the defaults don’t support dark mode very well. in our app, the dark purple handles on top of a primary dark mode background has only a 2.14:1 color contrast ratio (whereas in light mode the contrast is 8.98:1)

I agree with Comment #7, I think this is an important issue we should resolve (P2 at least).

Siyamed, if you / your team does not have time to look at this, feel free to assign to me - happy to take this over. As well as allowing changing the color, MaterialTheme should also be configured to set a color from the theme by default so that it is correct out of the box for typicaly use cases.

Thanks Louis.

Please keep in mind there are two main entry points: Text selection and TextField selection. as a note: In TextField it is possible that existing cursorColor defines those colors (or one of them)

it would be best to control selection as a whole for both of them I believe, but let's discuss it. Looks like material.TextField uses errorColor and activeColor as the cursor color. let's make sure we take that into account while designing the theming (they seem to be related)

open questions, assumptions that need verification:

• is cursorColor and selection color the same
• cursorColor is errorColor and activeColor in material.TextField, is there any relation
• Text and TextField should use a single selection color for consistency
• selection color is always the same for selection handle and selection background
• cursor color determines insertion (cursor) handle color as well (we do not have cursor handle yet)
• what the default color should be for light and dark mode
• shape of the cursor handle is not urgent, and possibly something we specifically don't want customization for the phone end user experience (similar to cursor animation)
• can there be a default color in foundation? choosing the text color, bg color etc too tricky. Using the exact text color wouldn't work since it would make text invisible.
