flutter_capture_vision_platform_interface

Common platform interface, value types, and versioned channel contract for the flutter_capture_vision federated plugin.

End users should depend on flutter_capture_vision instead of this package. This package exists for platform implementers and for the pure Dart contracts:

• Value types: VisionTask, VisionImageBuffer, VisionPixelFormat, VisionRotation, VisionPoint, VisionQuadrilateral.
• Requests: CaptureVisionRequest.forTasks / CaptureVisionRequest.namedTemplate (mutually exclusive).
• Results: CaptureVisionResult, BarcodeResult, MrzResult, DocumentDetectionResult — always typed lists, never null.
• Templates: CaptureVisionTemplate.parseAll(settingsJson) extracts CaptureVisionTemplates[].Name with order and case preserved, rejecting missing, blank, non-string, or duplicate names.
• Errors: CaptureVisionException(code, message, cause).
• Platform contract: CaptureVisionPlatform (all operations are Future-based) and the reference MethodChannelCaptureVision used by the native implementations.

See example/ for a runnable tour of the contracts without any native SDK.
