How to reproduce?

When I use wechat_assets_picker 8.4.2, when I open the picture selection page, the loading interface is stuck, and it is restored after a long time, and the thumbnail of the picture is not displayed.

Can you try if the issues can be resolved with these lines commented out?

flutter_photo_manager/android/src/main/kotlin/com/fluttercandies/photo_manager/core/utils/IDBUtils.kt

	context.contentResolver.openInputStream(uri)?.use {

I tried to comment out on the above code, but it didn't solve the problem, and the effect was the same as the video above.

[HongZhiQing]

It is normal for me to load thumbnails when I use the example project in flutter_photo_manager, while the example project using flutter_wechat_assets_picker cannot be loaded, or it will take a long time to load. Please see the video below.

Good to know about the difference. Can you differentiate the difference between their FilterOptionGroup to find which option causes the issue?

[HongZhiQing]

[HongZhiQing]

On the left is the FilterOptionGroup of the example project of flutter_photo_manager. I don't have the phone with the problem at present, and I can't tell which parameter is set wrong.

[HongZhiQing]

When I comment out the code in ``DefaultAssetPickerProvider```, as shown in the figure, I can load thumbnails normally. Is it because this phone has more than 3,000 photo albums? There are often many photo albums on Android phones.

You can try to set needTitle as false for image filter option.

any solution?

[AlexV525]

@HongZhiQing Do you still running into the same issue when using the latest version of this plugin and the picker?

[HongZhiQing]

I am not using the latest version, but the issue still exists in version 9.0.3.

[AlexV525]

fluttercandies/flutter_wechat_assets_picker#526 (comment) What about setting onlyAll for the filtering?

[AlexV525]

This should be solved by fluttercandies/flutter_wechat_assets_picker#596.

[HongZhiQing]

I'm glad to hear that
