flutter_lite_camera 0.2.3

A Flutter camera plugin for Android, iOS, web, Windows, macOS, and Linux with native previews and RGB frame capture.

0.2.3

• Android: captureFrame() honors the byteOrder argument again — 0.2.2 accidentally always used the GRB arrangement (2) regardless of the parameter.

0.2.2

• iOS/macOS: captureFrame() now converts based on the pixel format the capture pipeline actually delivered (kCVPixelFormatType_32BGRA/32RGBA/32ARGB) instead of always assuming BGRA. Some macOS camera drivers — virtual and third-party devices in particular — ignore the requested BGRA video setting, which previously produced channel-swapped (green/purple tinted) frames.
• Android: corrected the YUV→RGB conversion to the standard BT.601 full-range coefficients (the previous constants muted blue and distorted hue).
• Android: captureFrame() now converts the two chroma planes with their roles exchanged and writes the pixels in GRB order (byteOrder 2) — the combination verified against on-device reference colors. The previous literal plane assignment with RGB output rendered complement colors (blue objects turned pink).
• Android: captureFrame() accepts a byteOrder argument (0=RGB, 1=RBG, 2=GRB, 3=GBR, 4=BRG, 5=BGR; default 2) in case a device lays its chroma planes out differently.
• Android: captureFrame() snapshots the cached planes under one lock so luma and chroma always come from the same frame.

0.2.1

• Added Swift Package Manager support for the iOS and macOS implementations.
• Tightened the web dependency lower bound to the version required by the browser APIs used by the web implementation.
• Improved pub.dev package metadata.

0.2.0

• Added iOS, Android, and web implementations — one API across all six platforms.
• Zero-copy preview everywhere: a FlutterTexture fed by BGRA buffers on iOS/macOS, an engine SurfaceTexture on Android, and an embedded getUserMedia video element on the web. No frame data crosses the platform channel for display.
• Added buildPreview(textureId), which returns the correct preview widget per platform (a Texture on native, an HtmlElementView on the web). Prefer it over a raw Texture.
• Added getRotation() returning the clockwise degrees (0/90/180/270) to apply in Dart so the preview and decoded coordinates appear upright (typically 90 on iOS phones, 0 elsewhere — Android frames already arrive display-oriented, with coordinates mapping 1:1 onto the preview).
• Added a resolution API: the ResolutionPreset enum (low/medium/high/veryHigh/ultraHigh/max) plus setResolution(), setResolutionPreset(), getWidth() and getHeight(). Every platform negotiates the closest supported size instead of failing, and the actual size is always queryable. The example no longer hard-codes 640x480 and offers a preset picker.
• Android: requests the CAMERA runtime permission from open(); fixed preview failing to start and a display-orientation crash on API < 30.

0.1.0

• Added native texture preview on Windows, Linux, and macOS. The new startPreview()/stopPreview() methods render the video feed directly at the native layer through a Flutter texture, so frame data no longer crosses the platform channel for display.
• captureFrame() now reads from a native frame cache while the preview is running, so grabbing a frame for image processing does not disturb the video stream.
• Fixed RGB channel order: captureFrame() now returns true RGB888 on all platforms (Windows and Linux previously emitted BGR-ordered data).

0.0.2

• Fixed camera release issue for Windows.

0.0.1

• Initial release of the Flutter Lite Camera plugin.

• Add the following methods:

  • getDeviceList(): Returns a list of available camera devices.
  • open(int index): Opens the camera at the specified index.
  • captureFrame(): Captures a single frame as an RGB888 image.
  • release(): Releases the camera resources.
