Note: clientSecret field is required just for LinkedInUserWidget
Hybrid Composition vs Virtual displays (Android only) #
To get these values you need to create App on the LinkedIn.

Please check your minSdkVersion for different setup:
-- If you are using Hybrid Composition (default from version 2.1.0) your minSdkVersion should be at least 19
-- If you want to use Virtual displays (default before version 2.1.0) your minSdkVersion should be at least 20

To read more why this lib needs to use one of these two modes please visit docs of webview_flutter
Migration from 2.x.x library to 3.x.x #
Since LinkedIn introduce new way of signing in with LinkedIn called "Sign In with LinkedIn using OpenID Connect"
and they are deprecating and removing "Sign In with LinkedIn" from product list (see LinkedIn console where you have created your app)
this library needs to have few breaking changes duo change of architecture. Sorry for that in advance.

Projection property no longer exists since /me API is removed and from now on library is using /userinfo docs
Previous scopes are removed (r_emailaddress, r_liteprofile) and introduces new ones: openid, email, profile
All fields on user response are flatten (see example project) and some are not existing anymore
Response that you can get from LinkedIn with new API looks like this

{
"sub": "xxxx",
"email_verified": true,
"name": "xxxx",
"locale": {
"country": "US",
"language": "en"
},
"given_name": "xxxx",
"family_name": "xxxx",
"email": "xxxx",
"picture": "xxxx"
}

Samples #
You can see full example under this project.
Call LinkedIn authorization and get user object:
LinkedInUserWidget(
redirectUrl: redirectUrl,
clientId: clientId,
clientSecret: clientSecret,
onGetUserProfile:
(UserSucceededAction linkedInUser) {
print('Access token ${linkedInUser.user.token}');
print('First name: ${linkedInUser.user.givenName}');
print('Last name: ${linkedInUser.user.familyName}');
},
onError: (UserFailedAction e) {
print('Error: ${e.toString()}');
},
)
copied to clipboard
Or you can just fetch authorization code (clientSecret is not required in this widget):
LinkedInAuthCodeWidget(
redirectUrl: redirectUrl,
clientId: clientId,
onGetAuthCode:
(AuthorizationSucceededAction response) {
print('Auth code ${response.codeResponse.code}');
print('State: ${response.codeResponse.state}');
},
onError: (AuthorizationFailedAction e) {
print('Error: ${e.toString()}');
},
),
copied to clipboard
If you want to logout user (to clear session from webview) all you need is to forward true value
to property destroySession in LinkedInUserWidget or LinkedInAuthCodeWidget. Please don't forget to destroy your data in your local storage for this user. Currently, LinkedIn doesn't have API point on OAuth 2 which will destroy access token.
Properties that are available after call for LinkedInUserWidget #
String name;
String familyName;
String givenName;
bool isEmailVerified;
String sub;
String accessToken;
int expiresIn;
String picture;
String email;

Projection - No longer used duo deprecation and migration to OpenId #
Available from version 1.2.x #
Scopes - Enables you to define whatever scope you are needed #
Available from version 2.3.1 #
r_emailaddress and r_liteprofile scopes will be removed from LinkedIn after 30 of November and they are removed from library after 3.x.x version.
Now you should add under "Products" -> "Sign In With LinkedIn using OpenID Connect"
https://www.linkedin.com/developers/apps/{REPLACE_WITH_ID_OF_YOUR_APP}/products
OpenId is requiring openid scope with in combination of at least Email or Profile scope, but by default this library is adding three scopes
final scopes = const [
OpenIdScope(),
EmailScope(),
ProfileScope(),
],
copied to clipboard
You are also able to create custom scopes by extending Scope class
class CustomScope extends Scope {
const CustomScope() : super('whatever_scope_of_name_to_map_with_linkedin_api');
}

Best and shortest explanation why library is not supporting this is hidden behind this (comment)[https://github.com/d3xt3r2909/linkedin_login/issues/28#issuecomment-673357716]
If you have (access)[https://stackoverflow.com/a/57979607/6074443] to (developer partner program)[https://linkedin.zendesk.com/hc/en-us] I would really appreciate if you could submit pull request on this feature.

Firebase

As Firebase is not supporting LinkedIn out of the box this is not implemented inside the library and its heavy consuming time to implement custom solution, anyhow if someone is willing to submit PR I would really love to approve it

Web

Web is still not supported at it requires a lot of JS work, as LinkedIn doesn't allow that their API is injected into iFrame
