- Add parsePositiveInt(JSONObject, String
- Added _applyHiddenToChildren method to propagate hidden state to all children - Overrode hiddenProperty for ProxyViewContainer to call _applyHiddenToChildren when value changes - Updated _addViewToNativeVisualTree to apply hidden state to new children when container is hidden - Preserves isCollapsed behavior for layout calculations Fixes NativeScript#10912
- Test hiding existing children when proxy.hidden = true - Test showing children when proxy.hidden = false - Test hiding new children added after setting hidden = true - Test multiple children scenarios Fixes NativeScript#10912
- Accept main branch improvements for parsePositiveInt method - Use doubleValue() with Math.floor() for better numeric parsing - Add null check with object.isNull(key) - Use specific JSONException instead of generic Exception - Add documentation comment for numeric coercion

- import booleanConverter instead of using hiddenProperty.valueConverter - expose _applyHiddenToChildren so property handler can invoke it

What is the current behavior?
When
ProxyViewContainer.hidden = trueis set, the container'sisCollapsedproperty is set correctly for layout calculations, but the child views remain visible becauseProxyViewContainerhas no native view. Since children are directly added to the parent's native view tree, they need to have theirhiddenproperty set individually to be visually hidden.This is described in issue #10912.
What is the new behavior?
When
ProxyViewContainer.hidden = trueis set, the hidden state is now properly propagated to all child views, making them visually hidden. The fix:Added
_applyHiddenToChildrenmethod: Iterates through all child views and applies the hidden state to each one.Overrode
hiddenPropertyforProxyViewContainer: Registered a custom property handler that:isCollapsedfor layout calculations (preserving existing behavior)_applyHiddenToChildrento propagate the hidden state to all childrenUpdated
_addViewToNativeVisualTree: When a new child is added, if the container is already hidden, the child's hidden property is immediately set totrue.This ensures that when
ProxyViewContainer.hidden = trueis set, all existing and future children are properly hidden, matching the expected behavior.Fixes #10912.
