jet_cad_2d_flutter 0.7.4

Flutter rendering and interaction for the jet_cad_2d engine: a CAD canvas with camera, rulers, selection and snapping, and PDF and PNG export.

Changelog

0.7.4

• ViewportTransform.screenToWorldInto(sx, sy, out): screenToWorld into a caller's point, allocating nothing. SelectTool re-targets on a camera change through it.
• SelectTool.moveAdjuster (MoveAdjuster, null by default): a generic seam for a body move drag. It is told when a drag of a set begins (begin) and ends (end); on every retarget, after the snap chain and before the move, adjust may replace the target point (it gets the raw point, the drag's base, the ortho base while Shift pins an axis, whether the chain's point came from object snap, the pointer kind and Alt); it paints into the tool's overlay above the selection preview (paint); suppress tells it an attachment replaced the event's move; its changes listenable makes the tool re-target from the last screen point. The tool keeps the last pointer kind and Alt state for camera-driven re-targets. With no adjuster the tool behaves, and allocates, exactly as before.
• PaperPalette.guide (an optional constructor argument, null by default), guideColor (the effective colour: guide, else the built-in magenta for the paper, lightGuide 0xFFE0218A on a light paper, darkGuide 0xFFFF5CB0 on a dark one) and withGuide. ==, hashCode and the copies carry the field, so existing callers compile unchanged. It is the alignment guides' colour, distinct from preview (the move's base-to-target line).
• jet_cad_2d_plan 1.0.0's alignment guides use this seam and the palette colour; it depends on ^0.7.4.

0.7.3

• SelectTool passes the dragged selection as resolveDragPoint's new exclude while a move drag lives: a dragged object no longer snaps to its own pre-drag geometry.
• Depends on jet_cad_2d: ^0.7.3.

0.7.2

Screenshots and documentation, and one small change in the rulers. Plans are stored as in 0.7.1.

• RulerFrame passes the ambient DefaultTextStyle's font family to the rulers' labels and to the corner's unit symbol, so the rulers follow the host's text font. With no ambient family the labels are drawn exactly as in 0.7.1.
• Screenshots, in the pub.dev gallery and in the README: the canvas in light and dark, the selection's grips, the crossing band and the symbol gallery.
• The README has a package table and links the host guide.
• Funding links (GitHub Sponsors, Buy Me a Coffee) in the pubspec.
• Depends on jet_cad_2d: ^0.7.2.

0.7.1

The first release on pub.dev. The code is jet-cad 0.7.0's render package (git tag v0.7.0); what changed is how it is packaged: its own LICENSE (Apache 2.0), a README written for pub.dev, a runnable example, sdk: ^3.6.0, and its dependency on jet_cad_2d from pub.dev (^0.7.1).

From this release on, jet_cad_2d_flutter has its own version on pub.dev and its own git tags (jet_cad_2d_flutter-vX.Y.Z). Before it, the package was released with the other jet-cad packages under one version; that history is in the repository's CHANGELOG.md.
