The same for me!

It's happen too in:

MissingPluginException(No implementation found for method logOut on channel com.roughike/flutter_facebook_login)

Answer 2 · 2018-09-25T15:50:34.000Z

I restart the app an Work :)

Answer 3 · 2019-01-14T18:41:53.000Z

You need to do a "cold restart" to the app after adding the plugin to your pubspec.yaml. Meaning that you stop the app and then run it again.

@roughike Still not working.
Error:
MissingPluginException(No implementation found for method loginWithReadPermissions on channel com.roughike/flutter_facebook_login)

Answer 5 · 2019-09-05T22:14:47.000Z

@roughike Having the same issue here when doing

var loginResult = await _facebookLogin.logInWithReadPermissions(['email', 'public_profile']);

Cold-restarting the app does not solve the issue. Neither does uninstalling, cleaning and re-installing the app.

@roughike its working on android device but on iOS it's not working.Error:

Answer 7 · 2019-11-18T02:13:35.000Z

Any update on this? I also encountered this problem, tried restarting the app, different versions of the library & plugin, flutter clean, remove all the pub cache & podfile.lock, nothing works

Answer 8 · 2020-03-15T05:12:39.000Z

I've deleted the app on the simulator and iphone, cleared build, deleted pod folder and it worked.

Quit your app, and rebuild, if you want do a flutter clean, cold boot etc, it should work!

Hi @Yogi09,

I had similar issue than you. What worked for me is to make sure that the strings.xml was correctly formatted with the AppId. Follow this tutorial accurately and you will get it to work: How to integrate Flutter Facebook Authentication

I am also using this dependency: flutter_facebook_login: ^3.0.0 And it works fine.

Answer 19 · 2020-10-29T09:34:46.000Z

@NizarBsb I followed this tutorial and also after replacing my account FBAppID and protocol id copied same strings.xml file in the android, but still it is same. :(

Answer 21 · 2021-01-10T17:24:11.000Z

Please anyone solve this issue, getting the same error with shared preferences also, tried all rebooting, cleaning,rebuilding

Answer 23 · 2021-03-05T18:03:36.000Z

@satyamraj123 , for sharedPreferences you can easily solve that issue by adding the following code before you use sharedPreferences.
SharedPreferences.setMockInitialValues(<String, dynamic>{});

Answer 33 · 2023-11-16T17:57:13.000Z

I faced a similar problem with another library.
in android it was working fine. But in iOS I get channel error.
after spending lot's of time, I noticed inside
ios>Runner>GeneratedPluginRegistrant.m file, my plugin couldnot register it's channel.
so I add it manually to the file and it work.

to know exactly what names you need to choose for import look for library files

for other libraries it should be the same process.
