Example not working

[kentcb]

Hi,

Thanks for writing this plugin.

I cloned the example and ran it on Android (Pixel) with the Twitter app installed. I get the same behavior I'm getting in my actual app:

• the Twitter authorization view appears
• I tap Connect
• It says "Authenticating" then displays exactly the same Twitter authorization view
• I tap Connect again, it says "Authenticating" again, then it takes me back to the app. However, the future returned by authorize never completes
• If I tap Log in again, it errors with the below output in the debug console

Debugging the Java side, I can see that the activity is being recreated, so when onActivityResult is called, authClientInstance is null and the result is never forwarded to it.

I tried changing initializeAuthClient to this:

private TwitterAuthClient initializeAuthClient(String consumerKey, String consumerSecret) {
    if (authClientInstance == null) {
        authClientInstance = configureClient(consumerKey, consumerSecret);
    }

    return authClientInstance;
}

I updated the call sites but also changed onActivityResult to call it with my hard-coded key and secret (didn't know how to get them otherwise). This behaved in exactly the same way except that there is no longer an "Authorize already in progress" error when I try the second time.

🤔 Any ideas?

I get exactly the same behavior if I use the Flutter_Social_login by @YahiaAgwa here.

[pitazzo]

Exactly same error here, the problem is in final TwitterLoginResult result = await twitterLogin.authorize();

Any help will be appreciated

I got the same error of you @Pitazzo. When you try to print the message error shows "Failed to get request token" :/. Did you solve it?

Hi,

I solved this by following below:

It is important to configure the callback URLs so that everything works correctly in your application.

You will have to use the following callback URLs:

Android - twittersdk://

iOS - twitterkit-CONSUMERKEY://

FOR MORE INFORMATION READ: https://developer.twitter.com/en/docs/basics/developer-portal/guides/callback-urls.html

@x8Haider can you guide me exactly were to add "twittersdk://". I'm using firebase authentication with Twitter.
