daravel_google

English · Bahasa Indonesia

Google for Daravel: OAuth 2.0 user tokens that refresh themselves, service accounts (RS256 JWT, RFC 7523) and Google Calendar v3 with guests and Google Meet links. Tokens are stored in google/apiclient's JSON, so a Laravel and a Daravel application can share them.

dart pub add daravel_google

Application.configure(basePath: '.').withGoogle() // GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, ...

// A user's calendar, with the token stored at sign-in (refreshed when needed).
final calendar = Google.calendarFor(
  GoogleToken.parse(user.googleCred!),
  onRefresh: (fresh) async {
    user.googleCred = fresh.encode();
    await user.save();
  },
);

final event = await calendar.create(CalendarEvent(
  summary: 'Matematika XI',
  start: EventTime(DateTime(2026, 10, 28, 7, 30)), // in APP_TIMEZONE
  end: EventTime(DateTime(2026, 10, 28, 9)),
  attendees: [EventAttendee('siswa@sekolah.sch.id', displayName: 'Siswa')],
  meet: true,
));
print(event.meetUrl);

• GoogleOAuth: the consent URL (offline access), the code exchange, refresh and revoke; concurrent refreshes share one.
• GoogleServiceAccount: the key file, an RS256 assertion (checked byte for byte against OpenSSL), domain-wide delegation with subject.
• GoogleCalendar: create, get, list (every page), patch, replace and delete events; GoogleException carries Google's status and reason.
