Question 1

How do I handle permissions with photo_manager in Flutter?

Accepted Answer

Use PhotoManager.requestPermissionExtend() to request access, handling states like granted, limited, or denied. For limited access on iOS 14+, use presentLimited() to manage selections, as explained in the permission section.

Question 2

Can photo_manager filter assets by date or custom conditions?

Accepted Answer

Yes, use FilterOptionGroup with constraints like createTimeCondition, or CustomFilter for SQL-like queries with columns like CustomColumns.base.createDate. The README provides examples for advanced filtering.

Question 3

How do I display images from photo_manager in my app?

Accepted Answer

Use the AssetEntityImage widget or AssetEntityImageProvider from the photo_manager_image_provider package, specifying thumbnail size and format, as detailed in the display assets section.

Question 4

photo_manager vs image_picker: which one should I use for Flutter?

Accepted Answer

Use photo_manager for advanced media management with cross-platform filtering, Live Photo support, and write operations. image_picker is simpler for basic picking without native configuration but lacks these features.

Question 5

How to save a new image to the device gallery using photo_manager?

Accepted Answer

Call PhotoManager.editor.saveImage() with raw Uint8List data or saveImageWithPath() for existing files, but note platform limitations on supported file types like HEIC, as mentioned in the README.

Question 6

Does photo_manager support iCloud photos on iOS?

Accepted Answer

Yes, but files may need downloading; use PMProgressHandler with methods like loadFile to show progress indicators during retrieval, as iCloud assets can be slow to fetch depending on network conditions.
