// sub_scaffold.dart — 通用「返回箭头 + 标题」子页脚手架(六处收敛,视觉零变化)。
|
|
//
|
|
// 收敛自 account_screens.dart/orders_page.dart 的私有 `_SubScaffold`,以及
|
|
// purchase_page.dart/payment_page.dart/invite_page.dart/notifications_page.dart
|
|
// 里结构相同的内联等价实现。逐像素沿用原实现(同 padding/字号/图标),纯收敛非重设计。
|
|
//
|
|
// embedded=true 时只返回内容(desktop 内容区下钻,返回/标题由外层 shell 顶栏提供);
|
|
// 否则整页 Scaffold + SafeArea + 返回箭头行(mobile/tablet 全屏 push)。
|
|
// wrapPageBody=true 时由本组件把 child 套进 PageBody(桌面内容页统一宽度容器);默认
|
|
// false——调用方若已自行用 PageBody 包裹 child(如购买页需要 wide 变体),避免重复包裹。
