Change all children's font family in Flutter

Question

Is there a straight forward way to change the font family to a widget and all its children?

my thought was to have an inherited widget and store the font family and call it to get that when creating every text widgets and set its style, but I prefer a simpler way.

if you want juste for a party of widges, you have to create a shared style and use it with your widgets — Fatima ayaa, Apr 08 '21 at 15:51

You can wrap the widget whose descendants you want to change (e.g. MyWidget()) in a Theme Widget. For example:

Container(
 child: Theme(
          data: Theme.of(context).copyWith(
              textTheme: TextTheme(<your changes here>),
              ),
          child: MyWidget()
        )
)
