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]

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

[christocracy]

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 Do not quote the example version, quote the plugin version.

[MahmmoudSabri]

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]

Are you sure you ran Packages get?

[MahmmoudSabri]

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

[christocracy]

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]

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]

Works for me:

dependencies:
  image_picker: ^0.6.2+3

[prakashw3expert]

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]

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.
