WalkthroughText component initialization was refactored to use internal default props and explicit reset/dispose lifecycle steps; TextLayout and TextStyle gained mutable fields and update(options) methods, with constructors delegating to those update methods and color values copied on update.

270-280: Add comment explaining lineHeight validation.The validation
Math.max(fontSize, value)ensures line height is never smaller than font size, which is good defensive programming. However, adding a brief comment explaining this constraint would help future maintainers understand the reasoning.Apply this diff to add a clarifying comment:
setLineHeight (value: number): void { const fontSize = this.textStyle.fontSize; + // Line height must be at least fontSize to prevent text clipping const safe = Math.max(fontSize, value);

25-67: LGTM! Clean refactor to support dynamic reconfiguration.The refactor from readonly
maxTextWidthto mutable, combined with the newupdate(options)method, enables runtime reconfiguration of layout properties. The constructor delegation toupdate()follows the DRY principle and aligns with the parallel changes inTextStyle.packages/effects-core/src/plugins/text/text-style.ts (3)
75-81: LGTM! Consistent refactor pattern.The mutable
fontOffsetand constructor delegation toupdate(options)align with the refactor pattern inTextLayout, enabling consistent re-initialization across text components.
84-84: Good use of spread operators for color cloning.Using spread operators (
[...color]) to clone color arrays avoids shared references while minimizing garbage collection overhead compared to clone methods. This aligns with established patterns in the codebase.Based on learnings.
Also applies to: 99-99, 113-113
92-108: Excellent defensive reset pattern.Explicitly resetting outline, shadow, and font offset state before applying new options ensures clean re-initialization when
update()is called multiple times. This prevents stale values from persisting across updates.Also applies to: 118-119
packages/effects-core/src/plugins/text/text-item.ts (4)
88-104: Constructor refactor aligns with default props pattern.The constructor now initializes from default props instead of accepting incoming props, supporting the PR objective of enabling
item.addComponent()with default values. Canvas resource initialization remains consistent.
132-140: Good state reset pattern with proper texture cleanup.The
resetState()method properly disposes textures and resets internal state flags, ensuring clean re-initialization duringfromData()calls. The texture disposal check againstengine.whiteTexturecorrectly prevents disposal of the shared sentinel texture.
116-130: Proper lifecycle management in fromData().Calling
resetState()before applying new data ensures textures are disposed and internal state is reset, preventing resource leaks and stale state during re-initialization. This complements the new update-based initialization pattern.
185-201: Lazy initialization pattern supports flexible re-initialization.The lazy initialization of
textStyleandtextLayoutavoids unnecessary object creation while supporting both initial default-props construction and subsequent data-driven updates. This pattern integrates well with the newupdate()methods inTextStyleandTextLayout.

64-65: Replace deprecatedsubstr()withsubstring().The
substr()method is deprecated. Usesubstring()instead for future compatibility.Apply this diff:
- id: `default-id-${Math.random().toString(36).substr(2, 9)}`, - item: { id: `default-item-${Math.random().toString(36).substr(2, 9)}` }, + id: `default-id-${Math.random().toString(36).substring(2, 11)}`, + item: { id: `default-item-${Math.random().toString(36).substring(2, 11)}` },

88-104: LGTM! Clean initialization flow for parameterless construction.The constructor now properly supports
item.addComponent()without parameters by initializing canvas resources first, then applying default props. The initialization order is correct.
122-122: LGTM! Proper state cleanup before loading new data.Adding
resetState()before applying new data ensures texture resources are disposed and state variables are reset, preventing resource leaks.
132-140: LGTM! Well-structured cleanup method.The
resetState()method properly disposes texture resources and resets state variables, providing a clean slate for initialization or reinitialization.
170-171: LGTM! Empty constructor aligns with new initialization pattern.The empty constructor is appropriate since initialization now occurs through
updateWithOptions()called fromTextComponent's constructor, supporting the mixin pattern correctly.
177-193: LGTM! Efficient lazy initialization pattern.The change from always creating new
TextStyleandTextLayoutinstances to conditionally updating existing ones improves performance and aligns with the newupdate()methods added to those classes. This supports both initial construction and subsequent updates correctly.
