v3.0.16

3.0.16

• UILayoutEvaluator:

  • Fixed a null-check crash when a layout expression referenced an unresolvable element or
    this target (e.g. #missing.center.x). _evalMemberExpressionImpl and _evalThisImpl
    now return null instead of force-unwrapping a null resolved expression, so processLayout
    correctly falls back to its defaultValue.

• lib/src/component/capture.dart:

  • UICapture.getInputFile: hardened against a null HTMLInputElement.files, returning null
    instead of throwing (matching the null-safe handling already used in _readFile).

• Tests:

  • Added test/capture_test.dart covering the UICapture data-format conversion matrix
    (arrayBuffer/base64/string/dataUrlBase64), field value round-trips, null clearing
    and latin1 encoding.
  • Expanded test/layout_expression_test.dart with unit arithmetic, fallback-unit application,
    mixed-unit rejection and the unresolvable-element fallback (regression test for the fix above).
