flutter_flutter/sky/engine/core/css/CSSProperties.in

// This file specifies all the CSS properties we support and the necessary
// information for our code generation. The various supported arguments
// are described below with example usage

// We should remove all those marked OBSOLETE now
// We should remove all those marked LAYOUT once we have custom layout

// - alias_for=other-property
// Properties specifying alias_for do not get their own enum and instead map
// directly onto the CSSPropertyID they alias. Currently this means that the


// - runtime_flag=CSSFooProperty
// The flag on RuntimeEnabledFeatures conditionally enables the property


// - longhands=property;other-property
// The property is a shorthand for several other properties.


// Flags which go into CSSPropertyMetadata:
// - inherited
// The property will inherit by default if no value is specified, typically
// mentioned in specifications as "Inherited: yes"


// The remaining arguments are used for the StyleBuilder and allow us to
// succinctly describe how to apply properties. When default handlers are not
// sufficient, we should prefer to use converter, and failing that define
// custom property handlers in StyleBuilderCustom.cpp. We only should use
// StyleBuilderFunctions.cpp.tmpl to define handlers when there are multiple
// properties requiring the same handling, but converter doesn't suffice.

// - font
// The default property handlers call into the FontBuilder instead of setting
// values directly onto the RenderStyle

// - name_for_methods=BlendMode
// Tweaks how we choose defaults for getter, setter, initial and type_name.
// For example, setting this to BlendMode will make us use a setter of setBlendMode
// - initial
// The initial value accessor on the RenderStyle, defaults to e.g. initialBoxShadow
// - getter
// The RenderStyle getter, defaults to e.g. borderBottomLeft
// - setter
// The RenderStyle setter, defaults to e.g. setBorderBottomLeft
// - type_name
// The computed type for the property. Only required for the default value
// application, defaults to e.g. EDisplay

// - converter=convertRadius
// The StyleBuilder will call the specified function on StyleBuilderConverter
// to convert a CSSValue to an appropriate platform value

// - custom_initial
// - custom_inherit
// - custom_value
// - custom_all
// Handlers of the given types will be declared but not defined. Setting
// custom_all is equivalent to setting the other three flags

// - use_handlers_for=CSSPropertyTransform
// Use handlers for the specified property instead of defining new ones

// - builder_skip
// Ignore this property in the StyleBuilder

// - direction_aware
// This property resolves to a different property based on the current direction
// and writing mode.


// Properties with StyleBuilder handling

// High Priority and all other font properties.
// Other properties can depend upon high priority properties (e.g. font-size / ems)
