Type 'Future<dynamic>' is not a subtype of type 'Future<Map<String, double>>'

[foolzoom]

Hi! I have the kind of error, when I try to get location:

type 'Future<dynamic>' is not a subtype of type 'Future<Map<String, double>>' where Future is from dart:async Future is from dart:async Map is from dart:core String is from dart:core double is from dart:core

The first string of the stack trace:
#0 Location.getLocation (package:location/location.dart:12:16)

I too am getting this. I investigated further by hacking my own Location class, changing the signature of getLocation to:

Future<dynamic>

This got me past the problem statement leading to this:
...type '_InternalLinkedHashMap<dynamic, dynamic>' is not a subtype of type 'Map<String, double>' where...

So, it looks like:

 _channel.invokeMethod('getLocation');

Is returning an object of type:

_InternalLinkedHashMap<dynamic, dynamic>'

I hope this helps. For now, I will be tweaking my hacked version but I'd like to return to the proper version later.
If there is more investigation I can do for you, please ask.

I made a fix for this issue, and submitted a PR, but in the meanwhile, you can just point to my fork: https://github.com/efortuna/flutterlocation

I updated flutter to the latest version, after update am getting too many bugs like above, now how can I fix this issues.

Did you see my link? Put this in your pubspec.yaml:

location:
    git: git://github.com/efortuna/flutterlocation.git

do you want remove this flutter package location: "^1.1.7" and put your code or keep both ?

[efortuna]

Until my PR is accepted: #27... linking to my code is a stopgap to make your code work. You don't need the '^1.1.7' -- just the two lines I listed above.
