The web implementation of camera
.
Note: This plugin is under development. See missing implementation.
This package is endorsed, which means you can simply use camera
normally. This package will be automatically included in your app when you do, so you do not need to add it to your pubspec.yaml
.
However, if you import
this package to use any of its APIs directly, you should add it to your pubspec.yaml
as usual.
Find the example in the camera
package.
The camera devices are accessed with Stream Web API with the following browser support:
Accessing camera devices requires a secure browsing context. Broadly speaking, this means that you need to serve your web application over HTTPS (or localhost
for local development). For insecure contexts CameraPlatform.availableCameras
might throw a CameraException
with the permissionDenied
error code.
The device orientation implementation is backed by Screen Orientation Web API
with the following browser support:
For the browsers that do not support the device orientation:
CameraPlatform.onDeviceOrientationChanged
returns an empty stream.CameraPlatform.lockCaptureOrientation
and CameraPlatform.unlockCaptureOrientation
throw a PlatformException
with the orientationNotSupported
error code.The flash mode and zoom level implementation is backed by Image Capture Web API with the following browser support:
For the browsers that do not support the flash mode:
CameraPlatform.setFlashMode
throws a PlatformException
with the torchModeNotSupported
error code.For the browsers that do not support the zoom level:
CameraPlatform.getMaxZoomLevel
, CameraPlatform.getMinZoomLevel
and CameraPlatform.setZoomLevel
throw a PlatformException
with the zoomLevelNotSupported
error code.The image capturing implementation is backed by URL.createObjectUrl
Web API with the following browser support:
The web platform does not support dart:io
. Attempts to display a captured image using Image.file
will throw an error. The capture image contains a network-accessible URL pointing to a location within the browser (blob) and can be displayed using Image.network
or Image.memory
after loading the image bytes to memory.
See the example below:
if (kIsWeb) { Image.network(capturedImage.path); } else { Image.file(File(capturedImage.path)); }
The video recording implementation is backed by MediaRecorder Web API with the following browser support:
.
A video is recorded in one of the following video MIME types:
Pausing, resuming or stopping the video recording throws a PlatformException
with the videoRecordingNotStarted
error code if the video recording was not started.
For the browsers that do not support the video recording:
CameraPlatform.startVideoRecording
throws a PlatformException
with the notSupported
error code.The web implementation of camera
is missing the following features:
