Constructors

DVBox([Widget? child, DVModifier? modifier])
const
DVBox.audio(DVMediaSource source, {DVImage? artwork, DVMediaControls controls = DVMediaControls.standard, DVBackgroundPlayback background = DVBackgroundPlayback.none, bool autoplay = false, DVMediaSession? session, DVCaptions? captions, bool loop = false, DVMediaController? controller, DVModifier? modifier})
An audio player, as a box. See DVBox.video.
DVBox.camera({DVCameraLens lens = DVCameraLens.back, String? device, DVCameraControls controls = DVCameraControls.standard, void onPhoto(DVFile photo)?, void onVideo(DVFile photo)?, DVCameraController? controller, DVModifier? modifier})
A live camera, as a box: the preview, and a shutter, record, lens, flash and torch where the device has them.
DVBox.grid(List<Widget> children, {DVModifier? modifier, int columns = 2, double spacing = 8, bool responsive = true})
const
DVBox.horizontalScrollable(List<Widget> children, {DVModifier? modifier, double spacing = 8})
const
DVBox.image(Object source, {String? alt, double? width, double? height, BoxFit fit = BoxFit.cover, Widget? placeholder, DVModifier? modifier})
An image, as a box.
DVBox.list(List<Widget> children, {DVModifier? modifier, double spacing = 8, DVAlign align = DVAlign.start, DVCrossAlign crossAlign = DVCrossAlign.stretch})
const
DVBox.masonry(List<Widget> children, {DVModifier? modifier, int columns = 2, double spacing = 8, bool responsive = true})
const
DVBox.recorded({required DVWidgetRecorder recorder, required Widget child, DVModifier? modifier})
Whatever child draws, recordable: recorder.start() records it to an MP4 and recorder.start(streamTo: ...) streams it live. Nothing changes on screen; the box only marks what is recorded.
DVBox.row(List<Widget> children, {DVModifier? modifier, double spacing = 8, DVAlign align = DVAlign.start, DVCrossAlign? crossAlign})
const
DVBox.scrollableList(List<Widget> children, {DVModifier? modifier, double spacing = 8})
A vertical list that scrolls when its children do not fit.
const
DVBox.stack(List<Widget> children, {DVModifier? modifier})
const
DVBox.threePane(List<Widget> children, {DVModifier? modifier, double spacing = 16, DVThreePaneFold oneFold = DVThreePaneFold.firstAlone})
Three panes, one per panel of a tri-fold.
const
DVBox.twoPane(List<Widget> children, {DVModifier? modifier, double spacing = 16})
Two panes, one each side of the fold on a foldable.
const
DVBox.video(DVMediaSource source, {DVImage? poster, DVMediaControls controls = DVMediaControls.standard, DVBackgroundPlayback background = DVBackgroundPlayback.none, bool autoplay = false, DVMediaSession? session, DVCaptions? captions, bool loop = false, DVMediaController? controller, DVModifier? modifier})
A video player, as a box.
DVBox.wrap(List<Widget> children, {DVModifier? modifier, double spacing = 8, DVAlign align = DVAlign.start, DVCrossAlign crossAlign = DVCrossAlign.stretch})
Compatibility alias for DVBox.wrapLine; prefer wrapLine in new code.
const
DVBox.wrapLine(List<Widget> children, {DVModifier? modifier, double spacing = 8, DVAlign align = DVAlign.start, DVCrossAlign crossAlign = DVCrossAlign.stretch})
Canonical wrap layout for a static collection of children.
