Fixed Widget ID Generation (`widget_tree.dart`) +**Problem**: The ID generation logic was appending `.u` to every unwrapped layer, creating IDs like `root.0.u.u` instead of using the widget's key. + +**Solution**: Modified the unwrapping logic to preserve keys: +```dart +// BEFORE: +currentId = "${currentContext.id!}.u"; + +// AFTER: +if (builtResult.key == null || builtResult.key == currentWidget.key) { + // Keep ID but update context for the new widget type + currentContext = currentContext.spawn(builtResult, currentId); +} else { + currentId = "${currentContext.id!}.${builtResult.key}"; + currentContext = currentContext.spawn(builtResult, currentId); +} +``` + +### 2.

Enhanced Action Handler (`neon_app.dart`) +**Added robust logging**: +```dart +print('\n📥 RECEIVED ACTION 📥'); +print(' Target ID: $targetId'); +print(' Index: $index'); +print(' Value: $value'); +``` + +**Improved type conversion**: +```dart +// Switch/Checkbox: Handle both bool and string/int values +final newVal = value is bool ? value : (value == 'true' || value == 1); +widget.onChanged?.call(newVal); + +// Slider: Handle both num and string values +final newVal = value is num ? value.toDouble() : double.tryParse(value.toString()) ?? 0.0; +widget.onChanged?.call(newVal); +``` + +### 4. Fixed JSON Serialization (`widget_tree.dart`) +**Problem**: `double.infinity` (used in `Container(width: double.infinity)`) cannot be JSON-encoded. + +**Solution**: Added `_sanitizeDouble` helper: +```dart +dynamic _sanitizeDouble(double? value) { + if (value == null) return null; + if (value.isInfinite || value.isNaN) { + return -1.0; // Sentinel value for native apps + } + return value; +} +``` + +Applied to all double properties: `width`, `height`, `left`, `top`, `right`, `bottom`, `value`, `min`, `max`, `start`, `end`. + +### 5.
