You can use one of the state managements methods for variable passing between pages like provider or bloc.

More beginner and easy way for this is passing a variable to the widget you need to use with that variable.

For example:

class ProjectPage extends StatefulWidget {
  final String? variable_one;
  final int? variable_two;

  const ProjectPage({super.key, this.variable_one, this.variable_two});

  @override
  _ProjectPageState createState() => _ProjectPageState();
}

use Provider Package to create a global variable which can be accessible from anywhere in the code
