photo_zoom 0.1.0

photo_zoom: ^0.1.0 copied to clipboard

Initial release.

• PhotoView: pan, pinch zoom, double tap cycle, optional rotation, hero transitions, loading and error builders, and PhotoView.customChild for zooming an arbitrary widget.
• PhotoViewGallery: a PageView of photos, from a list or built on demand. Each page keeps its own zoom, and hands a drag to the page view once its photo is panned to the edge.
• PhotoViewController and PhotoViewScaleStateController: ValueNotifiers that read and drive the transform and the double tap cycle.
• PhotoViewScale: typed scale limits, either PhotoViewScale.value or a PhotoViewComputedScale.contained / .covered, with * and / to offset them.
• Zoom anchors at the touch, pointer or tap, rather than at basePosition.
• enableScrollZoom: mouse wheel zooms at the pointer and a two-finger trackpad scroll pans. Events that would change nothing are left to an ancestor scrollable.
• Zoom level and zoom actions exposed to screen readers; reduced motion honoured.

The API follows the photo_view package by Renan C. Araújo. See "Migrating from photo_view" in the README for the differences.
