RichText has different text size on some devices

I'm using RichText in my app but when I use it on some Android phones the text is bigger than when I use a Text with the same style.

How can I ensure that also RichText uses the same text size as Text?

Solution 1:

I found the answer. This error happens on devices with a different font size or display size. So the user has changed the text scaling for the whole OS (in my case to smaller). The framework - I guess Android - doesn't consider that for RichText. You have to manually apply the scale factor:

RichText(
    textScaleFactor: MediaQuery.of(context).textScaleFactor,
    text: TextSpan(''),
)
