Example

void main() async {

  // final tabPanel = TabPanel(defaultPage: YourDefaultPage());

  // or Create a more complex initial tab structure
  final tabPanel = TabPanel(
      defaultPage: PageA(),
      panels: [
        TabPanel(
          defaultPage: PageA(),
          panels: [],
          flex: 1,
        ),
        TabPanel(
          defaultPage: PageA(),
          axis: Axis.vertical,
          body: Container(color: Colors.blue),
          panels: [
            TabPanel(
              defaultPage: PageA(),
              panels: [],
              flex: 3,
              body: Container(color: Colors.green),
            ),
            TabPanel(
              defaultPage: PageA(),
              panels: [],
              flex: 1,
              body: Container(color: Colors.red),
            ),
          ],

          panels: [],
          flex: 1,
        ),

    ),
  );
}

Planned features and known issues

• Extend the Tab API to better control its navigation stack. Most things the built-in Navigator class has, and a few more.
• Integrate the Router class or write a custom implementation, for how to specify pages to be pushed.
• More customization options for panels and the tab bar and ability to set different themes for panels.
• Cupertino and Material versions.
• Adding an option to limit the level of nesting. Currently is unlimited.
• Clone tab
• Adding a new tabs does not scroll the tab bar to bring it into view. To be fixed soon.
