Adds initializeCamera implementation of the camera platform interface.

  • Added getVideoSize to Camera.
    • Returns a size of the camera video based on its first video track size.
  • Added initializeCamera and onCameraInitialized implementation.
    • Initializes and starts playing the camera stream.
    • Adds a CameraInitializedEvent to the camera events stream controller. The event is emitted on the onCameraInitialized stream and includes a camera id, video size, default exposure and focus modes (auto).
  • Replaced an HTTP stream with a blank canvas stream in tests that use a video element. In this way, tests are not reliant on the network and the video size can be easily adjusted.

Part of flutter/flutter#45297.

Pre-launch Checklist

  • I read the Contributor Guide and followed the process outlined there for submitting PRs.
  • I read the Tree Hygiene wiki page, which explains my responsibilities.
  • I read and followed the relevant style guides and ran the auto-formatter. (Note that unlike the flutter/flutter repo, the flutter/plugins repo does use dart format.)
  • I signed the CLA.
  • The title of the PR starts with the name of the plugin surrounded by square brackets, e.g. [shared_preferences]
  • I listed at least one issue that this PR fixes in the description above.
  • I updated pubspec.yaml with an appropriate new version according to the pub versioning philosophy.
  • I updated CHANGELOG.md to add a description of the change.
  • I updated/added relevant documentation (doc comments with ///).
  • I added new tests to check the change I am making or feature I am adding, or Hixie said the PR is test exempt.
  • All existing and new tests are passing.

@ditman Should this be reverted for now?

Correct, let's add a pass documenting all the web stuff in platform_interface later on, since we need to publish a new version of the platform_interface so the new docs show up in pub.

Makes sense to me. Let's go!

packages/camera/camera_web/example/integration_test/camera_test.dart
..width = 10
..height = 10;

final videoElement = getVideoElementWithBlankStream(Size(10, 10));
