Does this leverage offline plugin too https://docs.mapbox.com/android/plugins/overview/offline/ ?
When downloading large maps for offline use, user should be able to dismiss the application and download should continue.
iOS documentation of Mapbox SDK is scarce, I only found this: https://docs.mapbox.com/ios/maps/examples/offline-pack/
Not sure if there is also some kind of plugin that can be used, or if iOS SDK supports background downloads out of the box.
@m0nac0 do you have any insight on that?

+    },
+  );
+  Iterable regions = json.decode(regionsJson);
+  return regions.map((region) => OfflineRegion.fromJson(region)).toList();


As as suggestion, we could follow this article https://flutter.dev/docs/cookbook/networking/background-parsing
and put json parsing into compute, moving it to the background.

Same for other places that parse json

Hi, how is this PR ? any chances for merging ? I'm really waiting for this PR to be approved in order to use it

Amazing work @kleeb
Would you able to patch the remarks made?
Or if someone else is up for patching?

Looking forward getting this merged, apologies for the delay

Could you use offline-v9 instead? Plugins have the major version of the maps SDK appended to them.

Unfortunately not. We lost all developers that were contributing. Can any of you finish this up?

lfofelipe · 2020-11-12T04:12:21Z

Hi guys. I created a fork with the suggested corrections and I already merged with master (0.9.0). I have a project to go into production and I couldn't wait any longer. Whoever needs this functionality, can use my fork directly in the project while I do the PR correctly.
Replace the mapbox_gl package with proper indentation:

  mapbox_gl:
    git:
      url: https://github.com/lfofelipe/flutter-mapbox-gl.git
      ref: master

Comments:

To work on ios, fill in info.plist:

<key>MGLMapboxAccessToken</key>
<string>YOUR_KEY_HERE</string>

Sometimes the example screen "Offline Regions" is not working (I didn't have time to check why)
Tested on iOS and Android (virtual devices seem to give connection problems, test on real devices)

I will make corrections appropriately in the coming days.
If someone can create a PR by correcting the problem of the "Offline Regions" screen example from my fork, this would be absurdly quick to merge.

Besides assigning the information that the key should exist in the info.plist ...

lfofelipe · 2020-11-13T07:28:14Z

The issue "Sometimes the example screen "Offline Regions" is not working (I didn't have time to check why)" has been fixed on my fork

kleeb · 2020-11-13T14:16:12Z

@lfofelipe would you manage to solve all conflicts between my branch and your fork ?
This would speed up the process of putting it to master

@tobrun @m0nac0 what do you think ?

Sweet! Thanks a lot guys and all contributors.

gabeschine · 2021-01-03T18:03:28Z

Hey just wanted to say THANK YOU for your time implementing this feature. Nice work :).

philiplindberg · 2021-01-06T16:17:57Z

First of all, thank you @kleeb and contributors for implementing this awesome feature 👍

I did want to make you aware of a potential bug I found when testing the example app on iOS. In offline_regions.dart, if you use downloadOfflineRegionStream instead of downloadOfflineRegion to download a particular region, the following exception is raised on iOS:

PlatformException (PlatformException(Downloading error, The operation couldn’t be completed. HTTP status code 401, null, null))

Seems to be an issue with the Mapbox access token not being properly set, even though I've defined ACCESS_TOKEN in main.dart. Again, this only seems to be happening on iOS and with the downloadOfflineRegionStream method (as opposed to downloadOfflineRegion, which works fine).

Interestingly enough, I've found that setting MGLMapboxAccessToken in Info.plist to the same access token defined in main.dart prevents the exception from being thrown.

kleeb · 2021-01-07T15:21:05Z

Thanks @philiplindberg for letting me know. Will check on that.
If you manage to reproduce and fix would be also awesome.

tantzygames · 2021-02-12T21:54:21Z

I've been using Flutter_map and can cache a mapbox instance for each session, which is important as a user can open quite a few map views in my app, and mapbox charges for each time the access token is used.

I've been working towards swapping to Mapbox_gl, but it seems to require a new Mapbox instance every time a map is opened. I've tried to cache the MapboxMap, but it creates a new instance with a new controller each time.

As well as caching a region, could this also cache a Mapbox instance for a whole session?

AAverin · 2021-02-13T07:39:59Z

@Kretin1 I think this is tracked here #245
There is no solution yet to have single reusable instance, but using keepAlive mixin seemed to have worked for my case so far
