pseudo_ui 0.2.3

Server-Driven UI rendering engine for Flutter. Define UI with JSON Schema + View JSON, render natively with Material 3 widgets. 45+ components, expression engine, conditional visibility, LOV cascading [...]

0.2.3

• New: JSON-driven theme palette as public API. Consumers can now load a brand theme from a JSON document (Material Design Tokens / W3C Design Tokens style) without writing any Dart code:

  final raw = await rootBundle.loadString('assets/themes/acme.json');
  final palette = JsonPalette.fromJson(json.decode(raw));
  
  MaterialApp(
    theme: buildPseudoThemeData(palette: palette),
    home: PseudoView(...),
  );
  

  New public types:

  • PseudoColorPalette — abstract palette contract (20 Material 3 ColorScheme roles + success / warning / info status slots).
  • JsonPalette — PseudoColorPalette factory that reads a JSON map and exposes the brand colors as Dart Colors. Missing fields fall back to the M3 baseline.
  • DefaultMaterialPalette — built-in M3 baseline, used as the fallback for JsonPalette and as a sample to extend from.
  • buildPseudoThemeData(palette: ...) — Material 3 ThemeData builder that seeds a ColorScheme from the palette and attaches PseudoUiThemeExt for status colors.

• Spacer dispatch case added to DynamicRenderer. Supports both rigid mode (set width and/or height to render a SizedBox) and flex mode (set flex to expand inside a Row/Column). Previously rendered as an "unsupported" placeholder.

• Internal docs / inline references cleaned up so the package surface carries no internal project names. Publisher identifiers (@burgan-tech/pseudo-ui npm scope, repository URL, MIT copyright) are preserved as legitimate "who shipped this" signals.

• No breaking changes for existing consumers.

0.2.2

• Widen intl constraint from ^0.19.0 to >=0.19.0 <0.21.0 so consumers running on Flutter 3.27+ (which pins intl: 0.20.x via flutter_localizations) can adopt the package without dependency_overrides gymnastics.

0.2.1

• PseudoView now supports delegate: null for flat views with no actions, LOVs, or nested components. The engine falls back to a built-in NoOpPseudoViewDelegate.instance so consumers no longer need a stub delegate just to render JSON.
• NoOpPseudoViewDelegate exported from the public barrel for direct use. loadComponent still throws UnsupportedError when nested refs are encountered, surfacing the gap rather than rendering an incomplete tree.

0.2.0

• Add PseudoComponentRegistry — pluggable extension point for third-party component sets. The renderer's default branch now delegates to the registry, so any design system can register builders without touching DynamicRenderer.
• Add PseudoUiThemeExt — ThemeExtension<PseudoUiThemeExt> for semantic success / warning / info colors. Falls back to Material 3 defaults when not provided by the host.
• Theme awareness across the renderer: TextField/Dropdown/Card etc. respect host-provided InputDecorationTheme and ColorScheme.
• DynamicRenderer now exported from the public barrel so external builders can render nested children.
• Internal: design-system adapters extracted into a sibling package (not published to pub.dev — consumers register their own components via PseudoComponentRegistry).

0.1.3

• CI: use official dart-lang OIDC workflow for automated pub.dev publishing
• Package size optimized (13MB → 31KB) via .pubignore

0.1.2

• README: Initial data, Lookups, Data Model, Vocabularies sections added
• Code cleanup: silent catch fixed, empty action handlers wired, lint warnings resolved
• 101 unit and widget tests (up from 15)
• LOV reload optimization: skip unchanged params, skip static LOVs on field changes
• GitHub Actions CI + pub.dev automated publishing

0.1.1

• 45+ Material Design 3 component implementations
• Expression engine: $form, $instance, $param, $ui, $lov, $lookup, $schema, $item, $context
• Conditional engine: showIf/hideIf/enableIf/disableIf with 13 operators and compound rules
• Validation: JSON Schema validation (pattern, format, minLength, min/max) plus async custom validation
• LOV & Lookup: cascade filtering, smart reload (skip unchanged params)
• Overlay surfaces: Dialog, BottomSheet, SideSheet, NavigationDrawer driven by $ui state
• Nested components with isolated contexts and two-way data flow
• 101 unit and widget tests

0.1.0

• Initial release with core engine and basic Flutter adapter
