LoadingSpinnerState class

State management for Loading Spinner component Category 3: Non-Interactive Display (with Animation) States: Rest, Disabled

Loading spinner is a circular progress indicator with neumorphic styling that rotates continuously to indicate loading/processing state.

Extends BaseComponentState which provides:

• Neumorphic shadows (distance, blur, intensities, borderRadius)
• Animated border (showAnimatedBorder, borderColor, borderWidth)
• 20 override flags (4 states × 5 overrides)
• Shadow color helpers (getLightShadowColor, getDarkShadowColor)
• Effective property helpers (getEffectiveDistance, etc.)

Note: LoadingSpinner uses size instead of width/height, and has spinner colors.

Properties

animationDuration ↔ double

Animation duration in seconds (full rotation)

getter/setter pair

blur ↔ double

borderRadius ↔ double

Border radius is always size/2 for circular shape

getter/setter pair, inherited

componentNameGetter → String

Component identifier for theme color resolution. Each component should have a unique name like 'button', 'toggle', 'card'. Named componentNameGetter to avoid conflict with static componentName that some subclasses expose for external access.

Methods

addListener(VoidCallback listener) → void

Register a closure to be called when the object changes.

inherited

applyTheme(GeneratedPalette palette) → void

Apply colors from a GeneratedPalette to this component's state.

override

dispose() → void

Discards any resources used by the object.

inherited

getBaseColor(bool isDarkMode, String state) → Color

Get base color for a given state and theme mode

getComponentSpecificModifiedProperties() → Set<String>

Get set of component-specific modified properties. Called by getModifiedProperties() to include custom property tracking.

override

getDarkShadowColor(bool isDarkMode) → Color

Get the dark shadow color for neumorphic effects. Uses palette colors when available, falls back to defaults otherwise.

inherited

getDefaultDimensions() → ({double height, double paddingH, double paddingV, double width})

Get component-specific default dimensions. Returns a record with (width, height, paddingH, paddingV).

override

getEffectiveBlur(dynamic state) → double

Get effective blur for a given state (applies overrides if enabled). Accepts either String ('rest', 'hover', 'pressed', 'disabled') or ComponentState enum.

override

getEffectiveBorderColor(dynamic state) → Color

Get effective border color for a given state. Returns the animated border color. Override in subclasses for state-specific border colors. Accepts ComponentState enum or component-specific enum types.

inherited

getEffectiveBorderRadius(dynamic state) → double

Get effective border radius for a given state. Most components use the same border radius for all states. Override in subclasses for state-specific border radius. Accepts ComponentState enum or component-specific enum types.

inherited

getEffectiveBorderWidth(dynamic state) → double

Get effective border width for a given state. Returns the animated border width. Override in subclasses for state-specific border widths. Accepts ComponentState enum or component-specific enum types.

inherited

getEffectiveDarkIntensity(dynamic state, [bool isDarkMode = false]) → double

Get effective dark intensity for a given state. Single argument version - assumes light mode for backward compatibility. Accepts either String ('rest', 'hover', 'pressed', 'disabled') or ComponentState enum.

override

getEffectiveDistance(dynamic state) → double

Get effective distance for a given state (applies overrides if enabled). Accepts either String ('rest', 'hover', 'pressed', 'disabled') or ComponentState enum.

override

getEffectiveHeight(dynamic state) → double

Get effective height for a given state. Most components use the same height for all states, so this defaults to height. Override in subclasses for state-specific sizing. Accepts ComponentState enum or component-specific enum types.

inherited

getEffectiveLightIntensity(dynamic state, [bool isDarkMode = false]) → double

Get effective light intensity for a given state. Single argument version - assumes light mode for backward compatibility. Accepts either String ('rest', 'hover', 'pressed', 'disabled') or ComponentState enum.

override

getEffectiveWidth(dynamic state) → double

Get effective width for a given state. Most components use the same width for all states, so this defaults to width. Override in subclasses for state-specific sizing. Accepts ComponentState enum or component-specific enum types.

inherited

getLightShadowColor(bool isDarkMode) → Color

Get the light shadow color for neumorphic effects. Uses palette colors when available, falls back to defaults otherwise.

inherited

getModifiedProperties() → Set<String>

Get the set of property names that have been modified from defaults.

inherited

getSpinnerColor(bool isDarkMode, String state) → Color

Get spinner color for a given state and theme mode
