Tab overlay xaritasi

DeclarativeTabsScaffold

const tabHome = TabId('home');
const tabSettings = TabId('settings');

final pagesByTab = <TabId, List<PageEntry>>{
  tabHome: [const PageEntry(key: 'home', name: '/home')],
  tabSettings: [const PageEntry(key: 'settings', name: '/settings')],
};

return DeclarativeTabsScaffold(
  items: items,
  currentTab: currentTab,
  onSelectTab: _selectTab,
  pagesByTab: pagesByTab,
  setPagesForTab: _setPagesForTab,
  buildPage: _buildTabPage,
);
Cheklov

Har bir tab uchun, pagesByTab[tab] must stay non-empty chunki barqaror navigatsiya uchun ildiz sahifa zarur.
