Updates (OpenHarmony 3.1 Beta -> OpenHarmony 3.1 Release)
Added Validity Verification for Color Values in Color.json
Validity verification is added for color values in the color.json file. The verification rules are as follows:
- The hexadecimal color code is used in any of the following formats:
- #rgb: red(0-f) green(0-f) blue(0-f)
- #argb: transparency(0-f) red(0-f) green(0-f) blue(0-f)
- #rrggbb: red(00-ff) green(00-ff) blue(00-ff)
- #aarrggbb: transparency(00-ff) red(00-ff) green(00-ff) blue(00-ff)
- The dollar sign ($) is used to reference resources defined in the application. The format is as follows:
- $color:xxx
Change Impacts
If the verification rules are not met, an error is reported during compilation.
Key API/Component Changes
None
Restrictions on Declaring Multiple Data Types of State Variables
If a @State, @Provide, @Link, or @Consume decorated state variable supports multiple data types, they must be all simple data types or references at one time.
Example:
@Entry
@Component
struct Index {
// Incorrect: @State message: string|Resource = 'Hello World'
@State message: string = 'Hello World'
build() {
Row() {
Column() {
Text(`${ this.message }`)
.fontSize(50)
.fontWeight(FontWeight.Bold)
}
.width('100%')
}
.height('100%')
}
}
Change Impacts
When the defined state variable type contains both the simple data types and references, an error is reported during compilation.
Key API/Component Changes
If the defined state variable type contains both the simple data types and references, change the type to one of them, as shown in the preceding sample code.
