A simple flutter plugin to demo how to interact to system gallery. Only iOS PhotosKit is supported for now:
- get authorization status
- request Photos authorization status
- fetch assets metadata
- fetch assets' thumbnail image in binary form, then sent to flutter side
- (in example) display binary-form image with Image.memory
- Breaking API of 0.0.2
- changed deliverMode to PHImageRequestOptionsDeliveryModeOpportunistic for
[PHImageManager requestImageForAsset:targetSize:contentMode:options:resultHandler:]message. using PHImageRequestOptionsDeliveryModeFastFormat makes API only return very low resolution image. but using PHImageRequestOptionsDeliveryModeOpportunistic makes multiple calls to get different resolution images, so
- Because 2. has multiple calls to get images, in 0.0.2, the message handler is set inside Asset instance, but Dart's object doesn't have a deconstructor like method to call unregister message handler, and I move the example's AssetView into lib, and have the unregistering inside deactive of the Widget.
