After taking Picture Location is added successfully, but location map image is not appearing. It is still blank. Please refer screenshot for reference.
Below is the error log:

The following ClientException was thrown resolving an image codec:

The issue is that OpenStreetMap blocks requests that don't include a valid user-agent.

Fix (in your tileProvider headers):
tileProvider:NetworkTileProvider(headers: { 'User-Agent': 'MyFlutterMapApp/1.0 (contact@example.com)', 'Referer': 'https://myapp.example.com' },),
This makes your app compliant with OpenStreetMap's usage policy and avoids being blocked.

Full policy reference: https://operations.osmfoundation.org/policies/tiles/

Full Steps to make it work:

1. Fork or locally clone the package you're using (e.g. map_camera.dart or your tile wrapper).
2. In pubspec.yaml, point to the local path:
3. Inside that local package (in map_camera.dart or the file defining the TileLayer), locate the TileLayer widget and add
   tileProvider:NetworkTileProvider(headers: { 'User-Agent': 'MyFlutterMapApp/1.0 (contact@example.com)', 'Referer': 'https://myapp.example.com' },),
4. run flutter pub get.

I will open a pull request soon to address this properly inside the package.
