flutter pub add flutter_custom_cursor根據套件公開資料產生的選型評估，僅供參考。
一個 Flutter 套件，讓開發者能在桌面平台使用記憶體緩衝區設定自訂滑鼠游標。它能透過直接從記憶體載入游標資料，精確控制游標外觀，非常適合需要獨特或動態游標設計的應用程式。此套件專為 Windows、Linux 和 macOS 設計，可與 Flutter 的桌面目標無縫整合。支援進階游標自訂，不依賴外部檔案，提升 UI 設計的效能與彈性。

This plugin allows to create/set a custom mouse cursor directly from a memory buffer.
Big thanks to imiskolee to create the base of this plugin.
Note: Currently, the api required by this plugin on Windows is included in flutter master branch. It means that u need to use this plugin with flutter master branch on Windows platform. See flutter engine PR#36143 for details.
Update: the latest Flutter 3.7.0 does not contain PR above, which merges to flutter-3.7.0-candidate.2, while Flutter stable 3.7.0 is using flutter-3.7.0-candidate.1. This limitation will be lifted maybe in the next Flutter stable release.
// register this cursor
cursorName = await CursorManager.instance.registerCursor(CursorData()
..name = "test"
..buffer =
Platform.isWindows ? memoryCursorDataRawBGRA : memoryCursorDataRawPNG
..height = img.height
..width = img.width
..hotX = 0
..hotY = 0);
Note that a String cacheName will be returned by the function registerCursor, which can be used to set this cursor to system or delete this cursor.
CursorData.buffer is a Uint8List which contains the cursor data. Be aware that on Windows, buffer is formatted by rawBGRA, other OS(s) are rawPNG.
see the example project for details.
We have implemented the FlutterCustomMemoryImageCursor class, which is a subclass of MouseCursor. This class will automatically set the memory cursor for you. Keep it simple.
MouseRegion(
cursor: FlutterCustomMemoryImageCursor(key: cursorName),
child: Row(
children: [
Text("Memory image here", style: style),
],
),
),
You can delete a cursor with the cursorName.
await CursorManager.instance.deleteCursor("cursorName");
