ArkUI Subsystem Changelog
cl.arkui.1 Value Change of the PanelHeight Enum WRAP_CONTENT from 0 to ‘wrapContent’
Change Impact
Before the change, both customHeight(0) and customHeight(PanelHeight.WRAP_CONTENT) configure the component to adapt to the content height. After the change, customHeight(0) sets the content height to 0, and customHeight(PanelHeight.WRAP_CONTENT) configures the component to adapt to the content height.
Key API/Component Changes
The value of WRAP_CONTENT of the PanelHeight enum is changed from 0 to ‘wrapContent’. This API behavior change does not affect your use of the API.
cl.arkui.2 Change of the Default Value for aspectRatio Set to an Invalid Value or undefined
Change Impact
Before the change, if aspectRatio is set to a negative value or undefined, the default value 1.0 is used.
After the change, if aspectRatio is set to a negative value or undefined, the default value null is used. For example, if a <Row> component has only its width set and does not have any child component, then when aspectRatio is not set or is set to a negative value, the height of the <Row> component is 0.
