flutter pub add o_popup根據套件公開資料產生的選型評估，僅供參考。
o_popup 是一個 Flutter 套件，提供了一個疊加內容元件，可透過按返回按鈕或回到指標最初觸碰螢幕的位置來關閉。它支援點擊手勢，非常適合對使用者輸入有自然回應的互動式彈出視窗。彈出視窗會順暢地動畫進入並返回原始位置，提升跨平台的使用者體驗。特別適用於上下文選單、工具提示或針對 Android、iOS、Web、macOS、Windows 及 Linux 應用的暫時覆蓋層。

An overlaid content, which closes itself into opening place (on back button) or into the position where the pointer contacted the screen. It means, popup supports tap gesture!
First of all, you need to install the package.
The second step is to create a popup.
I recommend to use OPopupTrigger class
in order to simply create the popup as in the example.
It pushes OPopupOverlay widget
into Navigation stack, thus a user can dismiss the popup by back button
or by tapping anywhere on a screen.
In the OPopupTrigger class you can also set barrierDismissible
to false (to prevent dismissing popup by taping anywhere)
and for example create a button,
which pops the popup from Navigator stack (Navigator.of(context).pop())
in order to close the popup - like buttons in the example.
If you do not want to use OPopupContent class as a content of a popup triggered by OPopupTrigger
you should skip popupHeader and popupActionRow fields and set your own widget to
popupContent field. It gives you an ability to fully customize the content of the popup:
size, alignment etc.
You can also overwrite OPopupContent (create a class which extends OPopupContent),
customize it inside your own class and set your version of OPopupContent
to OPopupTrigger.popupContent
(also do not set popupHeader and popupActionRow in order to omit original OPopupContent).
