Constructors

NERtcVideoView({Key? key, int? uid, bool subStream = false, bool autoAttach = true, ValueListenable<bool>? mirrorListenable, NERtcVideoRenderer? renderer, NERtcVideoRendererEventListener? rendererEventLister, NERtcVideoViewFitType fitType = NERtcVideoViewFitType.cover, WidgetBuilder? placeholderBuilder, Color backgroundColor = const Color(0xFF292933)})

创建用户视频渲染组件。

const

NERtcVideoView.withExternalRenderer({Key? key, int? uid, bool subStream = false, bool autoAttach = true, ValueListenable<bool>? mirrorListenable, required NERtcVideoRenderer renderer, NERtcVideoRendererEventListener? rendererEventLister, NERtcVideoViewFitType fitType = NERtcVideoViewFitType.cover, WidgetBuilder? placeholderBuilder, Color backgroundColor = const Color(0xFF292933)})

创建用户视频渲染组件。

const

NERtcVideoView.withInternalRenderer({Key? key, int? uid, bool subStream = false, ValueListenable<bool>? mirrorListenable, NERtcVideoRendererEventListener? rendererEventLister, NERtcVideoViewFitType fitType = NERtcVideoViewFitType.cover, WidgetBuilder? placeholderBuilder, Color backgroundColor = const Color(0xFF292933)})

创建用户视频渲染组件。

const

Properties

autoAttach → bool

是否自动绑定画布。如果为 true，则在组件渲染时自动调用 NERtcVideoRenderer.attachToRemoteVideo 或 NERtcVideoRenderer.attachToLocalVideo 绑定画布到指定用户 uid。

final

backgroundColor → Color

视频组件背景色。如果用户视频不能填充整个组件的大小，则上下或左右会有留白，留白部分的颜色由该属性指定。

final

fitType → NERtcVideoViewFitType

视频画布缩放方式。

final

hashCode → int

The hash code for this object.

no setter, inherited

key → Key?

Controls how one widget replaces another widget in the tree.

final, inherited

mirrorListenable → ValueListenable<bool>?

视频镜像开关。组件会自动监听其修改，并在渲染时打开/关闭镜像。

final

placeholderBuilder → WidgetBuilder?

用户视频渲染可用之前的占位组件。

final

renderer → NERtcVideoRenderer?

视频渲染画布对象。如果为 null，则组件内部会自动创建和管理画布，并在组件销毁时自动释放画布。 开发者也可以通过 NERtcVideoRendererFactory.createVideoRenderer 手动创建一个画布，然后传入该参数，这样可以在多个组件中共享一个画布。 需要注意的是，如果使用了外部画布，开发者需要自己管理画布的生命周期，并在合适的时机 NERtcVideoRenderer.dispose 方法画布，否则会造成内存泄漏。

final

rendererEventLister → NERtcVideoRendererEventListener?

视频渲染事件监听器。

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

subStream → bool

指定渲染视频主流还是辅流。

final

uid → int?

指定需要渲染视频的目标用户。如果为 null，则渲染本地视频，否则渲染对应远端用户的视频。 如果渲染的是远端用户视频，需要业务层保证已经通过 NERtcEngine.subscribeRemoteVideoStream 订阅了该用户的视频流，否则会展示黑屏。

final

Methods

createElement() → StatefulElement

Creates a StatefulElement to manage this widget's location in the tree.

inherited

createState() → State<NERtcVideoView>

Creates the mutable state for this widget at a given location in the tree.

override

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A short, textual description of this widget.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
