Orodha za kurasa za kila tab

Manage Map<TabId, List<PageEntry>> for predictable tab navigation state.

Overlay kwa kila skrini

Use TabPageKey = (TabId, pageKey) to scope overlay state for each tab screen.

Mpangilio thabiti wa kurudi

Overlay -> pop ya staki ya tab -> tab ya kwanza -> onBackAtRoot.

Muundo wa Tabs Scaffold

Andaa root pages kwa kila tab na pitisha matukio yote ya tab kupitia masasisho ya state.

Ramani ya overlay ya tab

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,
);

Kizuizi

Kwa kila tab, pagesByTab[tab] lazima ibaki isiyo tupu kwa sababu root page inahitajika kwa tabia thabiti ya urambazaji.
