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.
