Add the textScaleFactor parameter

[timbotimbo]

A Text widget scales the font based on the textScaleFactor * fontSize.
If you never set this scale, it uses the value from the context, which is usually determined by the accessibility settings in android.

RichText doesn't seem to do use the context textScaleFactor by default, which makes simple_rich_text ignore it too.
So on some phones the rich text is a different size from any other text widgets.

Using a mediaquery RichText follows the behavior of normal Text widgets.

RichText(
    text: ,
    textScaleFactor: MediaQuery.of(context).textScaleFactor,
);

Can you add this parameter to the simple_rich_text constructor, and pass that to RichText?

Here is how you can manually set the global textScaleFactor in main to do some testing.

return new MaterialApp(
      //set global text scale factor in builder
      builder: (BuildContext context, Widget child) {
        final MediaQueryData data = MediaQuery.of(context);
        return MediaQuery(
          data: data.copyWith(textScaleFactor: 1),
          child: child,
        );
      },

Thanks for fixing it so quickly.

The current fix is fine for my use case, so you don't need to change anything. But for more flexibility in the future you might want the textScaleFactor to be customizable like the overflow and maxLines.

Something like
textScaleFactor: this.textScaleFactor ?? MediaQuery.of(context).textScaleFactor

I added it for completeness.
