GlassPathBridge class

Low-level FFI bridge for writing path data to native glass mask.

This bridge manages shared memory between Flutter and native code. Flutter writes path commands/points, native reads and applies as mask.

Thread safety:

  • frameIdPost is written FIRST (signals write in progress)
  • All data is written
  • frameId is written LAST (signals write complete)
  • Native reads frameId, copies data, reads frameIdPost
  • If frameId != frameIdPost, native skips frame (torn read)

Properties

Methods

createBuffer(String windowId, {int layerId = 0}) → bool
Create a path buffer for a window and layer. Returns true if successful.
destroyAllBuffers(String windowId) → void
Destroy all path buffers for a window.
destroyBuffer(String windowId, {int layerId = 0}) → void
Destroy the path buffer for a window and layer.
hasBuffer(String windowId, {int layerId = 0}) → bool
Check if a buffer exists for a window and layer.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
setDark(String windowId, bool isDark, {int layerId = 0}) → void
Set dark mode for a window and layer.
setEnabled(String windowId, bool enabled) → void
Enable glass effect for a window.
setMaterial(String windowId, int material, {int layerId = 0}) → void
Set the blur material for a window and layer.
setTintOpacity(String windowId, double opacity, {double cornerRadius = 16, int layerId = 0}) → void
Set tint opacity for a window's glass effect. A dark tint layer is added behind the glass to reduce transparency. opacity: 0.0 = fully transparent (default), 1.0 = fully opaque black cornerRadius: Corner radius for the tint layer (default 16)
toString() → String
A string representation of this object.
inherited
writePath({required String windowId, required List<GlassPathCommand> commands, required List<double> points, required double windowHeight, int layerId = 0}) → void
Write raw path commands and points to the buffer.

Operators

operator ==(Object other) → bool
The equality operator.
