To generate Google calendar events on the server-side using Flutter, you can follow these steps:
Set up a Google Cloud Platform (GCP) project and enable the Google Calendar API.
Create a service account in the GCP console and download the JSON key file associated with it.
Add the googleapis and googleapis_auth packages to your Flutter project. These packages provide the necessary APIs and authentication methods for working with Google services.
Initialize a client object with the JSON key file and the desired scopes (in this case, the Google Calendar API scope).
Create a new calendar event object with the required details such as start/end time, location, and description.
Use the client object to send a POST request to the Google Calendar API to insert the new event into the user's calendar.
Handle any errors that may occur during the API request.
Here's an example Flutter code snippet for generating a Google Calendar event:
import 'package:googleapis/calendar/v3.dart' as calendar;
import 'package:googleapis_auth/googleapis_auth.dart' as auth;
final _credentials = auth.ServiceAccountCredentials.fromJson({
"private_key": "<YOUR_PRIVATE_KEY>",
"client_email": "<YOUR_CLIENT_EMAIL>",
"client_id": "<YOUR_CLIENT_ID>",
"type": "service_account",
});
const _scopes = [calendar.CalendarApi.calendarScope];
final _client = await auth.clientViaServiceAccount(_credentials, _scopes);
final event = calendar.Event()
..summary = 'Test Event'
..start = calendar.EventDateTime()
..dateTime = DateTime.now().toUtc().add(Duration(hours: 1)).toIso8601String()
..timeZone = 'UTC'
..end = calendar.EventDateTime()
..dateTime = DateTime.now().toUtc().add(Duration(hours: 2)).toIso8601String()
..timeZone = 'UTC'
..description = 'This is a test event'
..location = 'San Francisco, CA';
final calendarApi = calendar.CalendarApi(_client);
try {
await calendarApi.events.insert(event, '<YOUR_CALENDAR_ID>').then((value) => print('Event created: ${value.htmlLink}'));
} catch (e) {
print('Error creating event: $e');
}
Note that you'll need to replace the placeholders in the code (denoted by angle brackets) with your own information, such as your private key, client email, client ID, and calendar ID. You can find the calendar ID by logging into your Google Calendar account and navigating to the settings for the desired calendar, then copying the "Calendar ID" value.
