camera-v0.12.0+1: [camera] Make Optional.of constructor const (#11247)

2026-03-19T15:06:43Z

Resolves old TODO from 2023 ( 6e09f5b committed by @camsim99 ) by making the Optional.of constructor const and removing the obsolete runtime ArgumentError.checkNotNull guard that was only needed during Dart 2's mixed-mode (unsound null safety) era. Mixed-mode execution was removed in Dart 3.0, so this is dead code. Not a breaking change.

Note that the entire Optional<T> class (and surrounding CameraController) is copy-pasted across 4 files in the camera packages. Would you prefer to move Optional<T> into camera_platform_interface to share it, or replace it entirely e.g. with a private sentinel pattern in copyWith (as the Flutter framework does for ThemeData)?

google_maps_flutter_android-v2.19.3: [google_maps_flutter_android] Batch clustered marker operations (#10940)

2026-03-18T15:35:04Z

Note: this PR attempts to use the same strategy from the Google Maps Flutter Web PR #10562 and apply it to Google Maps Flutter Android.

Summary

Adds batch addItems() and removeItems() methods to ClusterManagersController
Refactors MarkersController to batch add/remove/change operations for clustered markers
Reduces redundant re-clustering calls when multiple markers are added/removed/changed at once

This improves performance when working with large numbers of clustered markers by calling ClusterManager.cluster() once per cluster manager instead of once per marker.

Test plan

Added unit tests for batch add/remove operations
Added unit test for batch cluster manager changes
Existing tests pass

Addresses flutter/flutter#170573

web_benchmarks-v4.1.1: [web_benchmark] Fix tab connection for newer versions of Chrome (#11266)

2026-03-17T18:15:12Z

DevTools has been experiencing a flake with package:web_benchmark's launching of Chrome. I've also noticed several times a similar failure when running web engines locally.

Turns out (from trial and error) that newer versions of Chrome seem to establish the WIP connection before tabs have had a chance to open. It's a race between the two, and when the WIP connections is faster, we fail to find any tab to connect to, and therefore we fail. The fix in this PR is to allow a grace period of 5 seconds of retrying to find the tab.

I made a similar fix in the flutter/flutter repo.
