App <> Canvas - Improve connectivity

[longbmk]

There are some known issue about connection need to fix:

• [x] Do not scan for local devices if the phone is on a cellular network. @phuocbitmark
• [x] Scan for available canvases only one time after the user opens the app, within a background process @phuocbitmark
• [ ] ~Connection list at the init time takes too long time to scan devices~ @ppupha
• [ ] ~Connection between FFapp and TV app lost in FFapp if user kill the FFapp and reopen it~ @ppupha
• [x] Connection list does not display in iOS after clicking on Scan button to scan devices
• [x] Cannot cast Exhibition to TV app in specific device iP14pro in BMVN team (always happen).
• [x] Apply retry to all gRPC commands to make sure the command can be delivered in poor network conditions (e.g. on the edge of the wifi network coverage) @phuocbitmark
• [x] Add logging interceptors for gRPC to make sure we catch everything transmitted between the TV and the mobile app for debugging later on @phuocbitmark
• [x] Listen to TV status using gRPC streaming, and automatically sync the current status if the TV app changes to cast artwork from another phone. @ppupha
• [x] 2 connected devices can cast into 1 canvas app at the same time. @ppupha
• [ ] ~Sometimes, connection is lost in time casting an exhibition.~ @longbmk @ppupha
• [x] List of Canvas Devices does not sort by name
• [x] Default selecting casting device is 1st of list of devices. It should keep current selecting casting device @phuocbitmark

Connection list at the init time takes too long time to scan devices

For this issue, let's cache the list of local devices after scanning the first time, by using HiveBox with the key as the network BSSID. See how to get the network BSSID here: https://pub.dev/packages/network_info_plus.

Connection between FFapp and TV app lost in FFapp if user kill the FFapp and reopen it

For this issue, resetting the connection state is appropriate if the user deliberately terminates the app. But the app should cache the current connection in a HiveBox and restore it when the user resumes the app from the background. It is important to ensure that the connection resumes seamlessly when the app is reopened, even under conditions of low memory where some local or in-memory variables may be purged.

@Anais-bitmark Canvas feature can only be used if the phone is on wifi network. Please design a popup ask user to switch to wifi (same network canvas devices connecting to) when user is using cellular network and trying to cast canvas

@phuocbitmark Can it be treated as a UI improvement?
