The following programming patterns are discussed in this chapter:
- Loading resources asynchronously — Use the
Loadable
API to load metadata asynchronously for maps, layers, and other resources to do such things as monitor the load status of the resource, handle concurrent and repeated requests to load the resource, cancel a load, retry to load if previous attempts failed, and handle circumstances such as network outages or service interruption.
- Offline maps, scenes, and data — Explore a range of offline work patterns that you can implement to allow users to continue being productive when network connectivity is poor or nonexistent. The offline pattern you choose determines whether your users can define their own map area, and, if they are editing, how multiple editors will sync their edits back to a web map or back to a branch version.
Additional topics will be added in future documentation updates, but in the meantime Flutter Maps SDK developers can find useful guidance in the ArcGIS Maps SDK for Swift topics on Tasks and jobs and Performance considerations.
