Make schema contract and registry builders single-use after freeze. Move invalid color and breakpoint payloads into constraint validation, clarify deferred Tailwinds scope, and keep merge-hardening simplifications covered by tests.
…ayloads Broaden mix_schema styler codecs and wire mix_tailwinds to emit schema-validated payloads for accepted utilities. - Box decoration codecs now cover border, borderRadius, shape, backgroundBlendMode, and boxShadow; box/flex_box/stack_box stylers gain transform and transformAlignment. - Add Matrix4, Offset, BorderSide, Border, BoxShadow, Shadow, and TextHeightBehavior codecs; text styler covers textHeightBehavior, textDirectives, and TextStyle shadows. - Rework box constraints with explicit min/max bound validation so inverted bounds and unbounded minimums fail with stable errors. - TwParser routes accepted utilities through mix_schema payloads via tw_schema_payload(_policy).dart and parse*Payload APIs; mix_schema becomes a production dependency of mix_tailwinds. - melos analyze/ci run with --no-select for non-interactive CI.

Pin TwParser resolved-spec behavior across every property family, borders, gradients, breakpoints, !important, transforms, and the variant/breakpoint x transform intersection. Asserts concrete Flutter values (Matrix4, colors, EdgeInsets) under forced widget states and width-controlled MediaQuery; styler ==/toString rejected as non-deterministic. Regression net for the parser de-duplication refactor.
Extract the duplicated-meaning phases shared by _parseFlexDirect and _parseBoxDirect into single owners, behavior-preserving: - _applyChildWithTransforms: breakpoint/variant transform propagation (copyTo/needsIdentity/flush), previously copy-pasted in two branches - _flushBaseTransforms: the finalize-transforms tail - _classifyTokens + _Accumulators: the per-token classify/accumulate loop; flex hasBaseFlex/column() kept explicit via an onToken hook Parallel-distinct code left untouched (property switches, variant maps). Border-side/shadow hoists not viable (Dart non-regular F-bound on the style mixins) and left inline. Verified: 414 tests pass (incl. 79-case oracle), analyze clean, 17->15 clones.

…n logic - Add baseTokenOutsideBrackets() helper to extract token segment after variant prefixes - Refactor findFirstColonOutsideBrackets() and findLastColonOutsideBrackets() to share common logic - Extract _applyAccumulatedBoxLikeDecorations() to reduce duplication in flex and box parsing - Add tests for new baseTokenOutsideBrackets() function - Replace inline token extraction logic with helper calls
Route _extractMargin through TwResolver so P/H/text-element margins match the parser's handling of scale, prefixed, and arbitrary values (e.g. mb-[10px], mb-[1rem]). Negative margins are skipped because Padding's RenderPadding asserts non-negative insets, so emitting them would crash. Replaces the hand-rolled scale-lookup chain with the shared resolver and adds regression tests for arbitrary and negative margins.

Extract parser, theme, and translate layers into separate directories, introduce typed tw_types, and add parser purity and variants test suites. Remove legacy schema payload and semantic files in favour of the new layout.
…sing - Route widget-layer utilities separately from schema values - Parse tokens through TailwindCandidateParser in widget layer - Expand variant/breakpoint routing with breakpoint-aware resolution - Add tests for div/span widget layer and candidate parser coverage - Update FLUTTER_ADAPTATIONS for hex colors and percent handling

Description
Adds
mix_schema, an Ack-backed package that encodes and decodes Mix stylers (box, text, flex, stack, icon, image, flex_box, stack_box) to validated JSON wire payloads through aMixSchemaContract, with stable public errors, payload limits, scoped registries, and a draft-07 JSON Schema export. It also wiresmix_tailwindsto route accepted utilities through these schema payloads via newparse*PayloadAPIs, makingmix_schemaa production dependency.Changes
mix_schemapackage:MixSchemaContract, per-styler codecs, variant codec, scoped registries, error mapper, payload limits, and JSON Schema export.transform/transformAlignment, text height behavior, text directives, text/box shadows, and validated box constraints (inverted/unbounded bounds fail with stable errors).mix_tailwindsemits schema-validated payloads for accepted utilities (parseBoxPayload/parseFlexPayload/parseTextPayload) and addstext-alignsupport; unsupported utilities stay parser diagnostics.analyze/cirun non-interactively with--no-select.Review Checklist
