  }
}

Expected Behavior

adding any additional plugins (already used and worked in the same flutter version) worked without any problem

Actual Behavior

adding any new plugins in pubspec.yaml and use it the code , i get Unhandled Exception: MissingPluginException

Steps to Reproduce

1.add location: ^2.3.5 in pubspec.yaml Running "flutter pub get"
2.add this code in any file or in a new file

var _locationService = new Location();

bool serviceStatus = await _locationService.serviceEnabled();

3.you will got MissingPluginException

Context

i have MissingPluginException in several plugins or in any new plugin
for example

image_picker: ^0.6.2+3 , location: ^2.3.5 ,...

I do flutter clean and nothing changed
it's not about Flutter version because i do create a new project and i test one of those Libraries and everything was OK

Plugin version:1.4.3+14

There's no such version 1.4.3+14. This is the version of the /example app.

Latest version is 1.5.0.

MahmmoudSabri · 2020-01-07T10:15:50Z

yes i know but i meant that to know i download latest version of the example app.

christocracy · 2020-01-07T12:06:44Z

The /example is a folder within this repo. Do not quote the example version, quote the plugin version.

MahmmoudSabri · 2020-01-07T13:07:23Z

OK can you help me ? if you understand my issue?
i do download your example from github and i add a new plugin and this is my issue.

christocracy · 2020-01-07T13:11:02Z

Are you sure you ran Packages get?

MahmmoudSabri · 2020-01-07T13:25:53Z

yes I'm sure and the plugin is under External Libraries -> Flutter Plugins

christocracy · 2020-01-07T13:36:39Z

The /example imports 4 external dependencies. It has no problem using those.

Anyway, why are you importing the location package? Background Geolocation does everything it does and more. You don't need that.

MahmmoudSabri · 2020-01-07T13:44:33Z

why not?i want to import any library, it seems there is something wrong or comparability issue,
can you import this library or image_picker and test it?

christocracy · 2020-01-07T15:01:19Z

Works for me:

dependencies:
  image_picker: ^0.6.2+3

prakashw3expert · 2020-01-09T07:48:34Z

MissingPluginException(No implementation found for method listen on channel
IOS device
why i am getting this error in my project accessing the same library.
Plz give me solution fast.

christocracy · 2020-01-09T14:28:42Z

I made a new "hello world" project with latest flutter_background_geolocation, implemented Android headless-task and imported image_picker. It works fine on both iOS and Android.

Closing this issue after a prolonged period of inactivity. Fell free to reopen this issue, if this still affecting you.

flutterboi · 2021-02-16T21:34:36Z

hey, I am having this issue as well

christocracy · 2021-02-16T21:40:02Z

@flutterboi You are providing zero information. See the first post in this thread for interesting information to provide.

flutterboi · 2021-02-16T21:51:23Z

I am using the same location plugin as OP. See the original post. This plugin does not work in congruence with the other location plugin.

christocracy · 2021-02-16T22:08:16Z

I am using the same location plugin as OP

There's no way you're using the same version.

I'm not thinking about this closed issue until you provide all the required info as in OP.
