[BuildCodelessly]

Model changes found while recreating a code-built app (Crate Digger, a vinyl collection with a turntable) in the Codelessly editor. Every gap the editor hit is logged with its fix in the editor repo's references/crate_digger/blockers.md.

What's new

• Motion (BaseNode.motion, MotionModel):

  • offset, scale, opacity, rotation, 3D tilt with perspective and origin;
  • an animated transition and continuous spin;
  • loop, enter, enterFrom, delayMs and a bindable replayKey.

  Values bind as motion.<name> variables.

• Triggers:

  • timer (intervalMs) and keyPress (key) on canvases;
  • swipes, doubleTap, hoverEnter and hoverExit on frames, rectangles, buttons, icons and text.

  Master's valueChanged and debounceMs are kept alongside.

• Layout:

  • ListViewProperties.stacked and wrap with spacing and alignment;
  • sliders with orientation, inverted, a thumb stroke and a roundedRect thumb;
  • the row/column gap this branch first added as itemSpacing now uses master's spacing. RowColumnNode.fromJson reads itemSpacing in older JSON as spacing.

• Variables:

  • computed variables use master's model: the value is a ${= ...} formula and isComputed reports it. A formula key in older JSON moves into value (withFormulaAsValue);
  • bindable effectsVisible, strokeWeight, cornerRadius, fontWeight and a slider's min/max.

• JSON:

  • variableSyntaxIdentifierPattern matches a ${= ...} formula whole, object literals included;
  • EdgeInsetsModel.fromJson reads {left, top, right, bottom} and {horizontal, vertical};
  • lists and placeholders read JSON without their editor-only keys.

• Release: version 6.2.0, with one CHANGELOG entry covering master's changes and this branch's.

Checks

Run locally the way CI runs them, on the merge with master:

• generated code is up to date;
• dart format;
• dart analyze --fatal-infos;
• dart test: 323 pass;
• dart pub publish --dry-run: 0 warnings.

Merge order

1. Merge this PR, then publish codelessly_api 6.2.0 to pub.
2. Merge the SDK PR (codelessly_sdk 8.3.0: motion, formulas, computed variables, triggers, layout CodelesslySDK#80). Its CI resolves codelessly_api ^6.2.0 from pub, so it can only go green after step 1.
3. Merge the editor PR (Codelessly/CodelesslyEditor#706) after pointing its submodules at the merged commits.
