camera_android #

The Android implementation of the camera plugin.

This package provides low-level camera access for the Android platform, used internally by the camera plugin.

🚀 New Feature: Capture Preview Frame #

This version introduces a new platform method: capturePreviewFrame(), which allows retrieving a single JPEG frame from the camera preview without taking a full-resolution photo.

✅ Use Cases #

• Fast frame grabs for processing or analysis
• Lightweight snapshot preview without shutter delay
• ML/AI scanning without full capture overhead

🛠 How It Works #

• Internally uses an additional ImageReader with YUV format.
• Maintains low latency (~10–50ms) compared to takePicture().
• Avoids interrupting the preview or recording session

🔧 Flutter Usage (via Pigeon) #

final data = await cameraController.capturePreviewFrame();
// `data` is a CamereImageData

🔹 startListenFrames() / stopListenFrames #

   await cameraController.startFrameStream((frame) {
    // process
      });
