CodePudding user response：

You can use the getters available in FirebaseUser.

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

String name = user.getDisplayName();
String email = user.getEmail();

CodePudding user response：

You can use the FirebaseAuth instance to get user info:

Future<Map<String,dynamic>> _getUserDetails(){
       FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();
    
       if(user != null){
       return {
        'name' : user.getDisplayName(),
         'email' : user.getEmail();
         }
        }
      
    
     return {
      'name' : 'No name',
     'email' : 'No email'
    }

}
