像这样包裹起始选项卡：

Align(alignment: Alignment.centerLeft,child: Tab(text: AppLocalizations.of(context)!.products, icon: SvgPicture.asset('assets/svg_icons/saved_tab_icons/products.svg'),),)

和结束标签如：

Align(alignment: Alignment.centerRight,child: Tab(text: AppLocalizations.of(context)!.looks, icon: SvgPicture.asset('assets/svg_icons/saved_tab_icons/looks.svg'),),)
