iOS Simulator and Real device have different results

[brianp]

Describe the bug
When using requestType with RequestType.video I get different results in the iOS simulator than on a real device. In the iOS simulator, only video assets are returned. This is the correct behaviour. When the flutter app is built in release mode and used on a real iOS device (iPhone XR, OS: 16.6) all media is available to select. Filtering for video-only assets is not functioning.

How to reproduce

AssetPicker.pickAssets(context,
  pickerConfig: const AssetPickerConfig(
    maxAssets: 1,
    requestType: RequestType.video,
))

Steps to reproduce the behavior:
On a real iOS device

1. Trigger the asset picker
2. See that all assets are available, not filtered by asset type.

Expected behavior

1. Trigger the asset picker
2. See only video assets

Version information

1. Device: iPhone XR
2. OS: iOS 16.6

1. Simulator iPhone XR
2. OS: iOS 16.4

---

• Package Version: 8.7.1
• Flutter Version: 3.13.6

Additional context
Behaviour in the simulator is not the same as behaviour on real device. Validating this incorrect behaviour is not possible on the simulator, as it will provide the expected result.

Cheers mate!

For anyone finding this later on. The link provided suggests the problem is that livephotos are included as "video" by default. This meant on my real device I had significantly more media displaying than expected. You need to pass an ios specific option to filter out livephotos as well.

I changed my code from the above example to the following, and got my expected result:

AssetPicker.pickAssets(context,
  pickerConfig: AssetPickerConfig(
    maxAssets: 1,
    requestType: RequestType.video,
    filterOptions: FilterOptionGroup(containsLivePhotos: false),
))

	- When `requestType` equals to `RequestType.video`,
	the picker will obtain *Live Photos* on iOS by default.
	You can disable it by setting `FilterOptionGroup.containsLivePhotos`
	to `false`.
