Flutter Google Calendar

In order to integrate Google Calendar in a Flutter application, you can make use of the googleapis and googleapis_auth packages. Follow the steps below:

1. Add the googleapis and googleapis_auth dependencies to your pubspec.yaml file:

dependencies:
  flutter:
    sdk: flutter
  googleapis: ^10.0.0
  googleapis_auth: ^1.2.0
    

2. Run flutter packages get to fetch the packages.
3. Import the necessary packages in your Dart file:

import 'package:googleapis_auth/auth_io.dart' as auth;
import 'package:googleapis/calendar/v3.dart' as calendar;
    

4. Obtain the required OAuth 2.0 credentials from the Google Cloud Console. Create a project and enable the Google Calendar API. Then, create an OAuth 2.0 client ID and download the JSON file containing the credentials.
5. Load the credentials from the JSON file and authenticate:

final credentials = await auth.clientViaServiceAccount(
  auth.ServiceAccountCredentials.fromJson({
    'private_key': 'YOUR_PRIVATE_KEY',
    'client_email': 'YOUR_CLIENT_EMAIL',
    'client_id': 'YOUR_CLIENT_ID',
    'scopes': [calendar.CalendarApi.calendarScope]
  }),
);
    

Replace the values in the fromJson method with the appropriate values from your JSON file.

6. Create an instance of the Calendar API using the authenticated credentials:

final calendarClient = calendar.CalendarApi(credentials);
    

7. Now, you can perform various operations on the Google Calendar. For example, to list all calendar events:

final calendarId = 'primary'; // Use 'primary' for the user's primary calendar
final calendarEvents = await calendarClient.events.list(calendarId);
for (var event in calendarEvents.items) {
  print(event.summary);
}
    

Remember to handle any necessary authentication and authorization flows in your Flutter application before accessing the Google Calendar API.
