Add Google Meet integration to meeting creation #151
Conversation
📝 WalkthroughWalkthroughThis pull request integrates Google Meet link creation directly into the meeting creation screen. A new GoogleMeetService handles OAuth authentication and Calendar API calls to generate Meet links, while the UI adds a button to trigger link creation with loading feedback and validation. Changes

valid when non-null, but `createMeetLink` can return an empty string; update the
guard in the block that sets `_urlController.text` and calls `_checkUrl` to
verify the link is both non-null and non-empty (e.g., use `link != null &&
link.isNotEmpty`) before assigning `_urlController.text = link` and invoking
`_checkUrl(link)` so you don’t populate the field with an empty string.

onPressed handler (the widget rendering the "Create Meeting" action in

null when true (same pattern used in the Create Google Meet Link button),

states and SnackBar messages for success and failure cases. Use the service
class name GoogleMeetService and the private flow method name
_createGoogleMeetLink (or the public handler that calls it) to locate code, and
employ mocking libraries (mockito or mocktail) and flutter_test widget testers
to assert UI feedback and interactions.

- Around line 35-36: The code currently hardcodes a 1-hour expiry when
constructing AccessCredentials/AccessToken; instead, obtain the real expiry if
available from the GoogleSignInAuthentication response (e.g., an expiresIn
field) and use that to compute the DateTime, and if no expiry is exposed fall
back to a conservative short TTL (e.g., a few minutes) or force a fresh token
request; update the AccessCredentials/AccessToken creation to use
DateTime.now().toUtc().add(Duration(seconds: expiresIn)) when expiresIn is
present (and use a short fallback when absent) so the token lifetime is not
incorrectly assumed.
- Around line 69-76: The current return expression can yield an empty string
(EntryPoint(uri: '')) which is treated as non-null by the caller
(_createGoogleMeetLink) and causes a false-success; change the fallback so that
when there is no hangoutLink and no video entry in
createdEvent.conferenceData?.entryPoints you return null instead of an
EntryPoint with an empty uri. Locate the expression using
createdEvent.hangoutLink and the firstWhere(orElse: () => cal.EntryPoint(uri:
'')) and replace the orElse/uri usage with logic that returns null when no video
entry exists (or check for existence before returning .uri) so callers see a
true null and can handle the missing link correctly.
🧹 Nitpick comments (5)
lib/services/google_meet_service.dart (4)
7-11: Redundant scope:calendarEventsScopeis a subset ofcalendarScope.
CalendarApi.calendarScopealready grants full read/write access to calendars and events. RequestingcalendarEventsScopealongside it is redundant and unnecessarily broadens the displayed consent screen text.Suggested fix
final GoogleSignIn _googleSignIn = GoogleSignIn( scopes: [ cal.CalendarApi.calendarScope, - cal.CalendarApi.calendarEventsScope, ], );
20-32: CallingsignIn()on every link creation forces the account picker each time.
signIn()presents the interactive sign-in/account-chooser flow. For returning users who already granted consent, this is unnecessary friction. PrefersignInSilently()first, falling back tosignIn()only when needed.Suggested fix
- final account = await _googleSignIn.signIn(); + var account = await _googleSignIn.signInSilently(); + account ??= await _googleSignIn.signIn(); if (account == null) return null;
30-31: Replaceprint()withdebugPrint()or a structured logger.Bare
print()statements are not stripped in release builds and can leak operational details. The rest of the codebase (e.g.,create_meeting_screen.dartLine 216) usesdebugPrint.Suggested fix
- print('No access token available'); + debugPrint('No access token available');- print('Error creating Google Meet link: $e'); + debugPrint('Error creating Google Meet link: $e');You'll also need to add:
import 'package:flutter/foundation.dart';Also applies to: 80-82
86-88: Remove dead code or wire up thesignOut()method.The
signOut()method inGoogleMeetServiceis defined but never called anywhere in the codebase. Either remove it if disconnecting Google accounts is not a required feature, or implement the UI wiring to invoke it when users attempt to sign out.lib/screens/meetings/create_meeting_screen.dart (1)
51-90: Duplicated date/time combining and duration parsing logic.Lines 63–69 and 82–90 are near-identical copies of the same logic in
_createMeeting(Lines 171–177 and 180–187). Extract shared helpers to reduce duplication and prevent future drift.Example helper extraction
DateTime _buildMeetingDateTime() { return DateTime( _selectedDate!.year, _selectedDate!.month, _selectedDate!.day, _selectedTime!.hour, _selectedTime!.minute, ); } int _parseDuration() { try { final d = int.parse(_durationController.text.trim()); return d > 0 ? d : 60; } catch (_) { return 60; } }Then use
_buildMeetingDateTime()and_parseDuration()in both_createGoogleMeetLinkand_createMeeting.

Guard against empty-string Meet link from the service.
As noted in the service review, createMeetLink can return "" instead of null. Even after fixing the service, a defensive check here prevents a broken link from silently populating the URL field.
Suggested fix
- if (link != null) {
+ if (link != null && link.isNotEmpty) {
_urlController.text = link;
_checkUrl(link);📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Button UI and loading state look correct.
The button is properly disabled during link creation, shows a CircularProgressIndicator in-flight, and the label updates to indicate progress. This aligns with the issue requirement for loading states.
One minor UX note: the "Create Meeting" button (Line 512) is not disabled while _isCreatingMeetLink is true, so a user could submit the form mid-generation. Consider disabling it as well.

Add unit and widget tests for Google Meet functionality.
The codebase currently has only a basic counter smoke test. Tests for GoogleMeetService (mocking Calendar API interactions) and widget tests verifying button states and snackbar feedback for the _createGoogleMeetLink flow are missing and required per the PR objectives.

Hardcoded token expiry is unreliable.
The actual access token lifespan is determined by Google's auth server and may differ from the assumed 1-hour window. google_sign_in does not directly expose the real expiry. If the token is already partially expired by the time this code runs, the AccessCredentials object will carry a stale estimate. This is unlikely to cause issues for a single short-lived API call, but be aware this is a best-guess.

Fallback can return an empty string instead of null, breaking the caller's null-check.
When hangoutLink is null and entryPoints has no video entry, orElse returns EntryPoint(uri: ''). The caller (_createGoogleMeetLink) checks if (link != null) — an empty string passes that check, so the URL field gets set to "" and a "success" snackbar is shown with no usable link.

Closes #150
📝 Description
This pull request improves the meeting creation experience by enabling Google Meet link generation directly within the Ell-ena app. Users can now create a Google Meet link on the same screen without switching to the Google Meet or Google Calendar app. The generated Meet URL is automatically filled, making the overall flow faster, smoother, and more user-friendly.
