1.shaderStyle(shader: ShaderStyle)

可以显示为径向渐变RadialGradientStyle或线性渐变LinearGradientStyle或纯色ColorShaderStyle的效果，shaderStyle的优先级高于fontColor和AI识别，纯色建议使用fontColor。当center设置到组件范围外时，可将repeating设置为true查看现象。

2.使用案例

@Entry
@Component
struct ShaderColorStyle {
  @State message: string = 'Hello World';
  @State linearGradientOptions1: LinearGradientOptions =
    {
      angle: 45,
      colors: [[Color.Red, 0.0], [Color.Blue, 0.3], [Color.Green, 0.5]]
    };
  @State linearGradientOptions2: LinearGradientOptions =
    {
      direction: GradientDirection.LeftTop,
      colors: [[Color.Red, 0.0], [Color.Blue, 0.3], [Color.Green, 0.5]],
      repeating: true,
    };
  @State radialGradientOptions: RadialGradientOptions =
    {
      center: [50, 50],
      radius: 20,
      colors: [[Color.Red, 0.0], [Color.Blue, 0.3], [Color.Green, 0.5]],
      repeating: true,
    };
  @State colorShaderStyle: ColorShaderStyle =
    {
      color: Color.Blue
    };
  build() {
    Column({ space: 5 }) {
      Text('angle为45°的线性渐变').fontSize(18).width('90%').fontColor(0xCCCCCC)
        .margin({ top: 40, left: 40 })
      Text(this.message)
        .fontSize(50)
        .width('80%')
        .height(50)
        .shaderStyle(this.linearGradientOptions1)
      Text('direction为LeftTop的线性渐变').fontSize(18).width('90%').fontColor(0xCCCCCC)
        .margin({ top: 40, left: 40 })
      Text(this.message)
        .fontSize(50)
        .width('80%')
        .height(50)
        .shaderStyle(this.linearGradientOptions2)
      Text('径向渐变').fontSize(18).width('90%').fontColor(0xCCCCCC)
        .margin({ top: 40, left: 40 })
      Text(this.message)
        .fontSize(50)
        .width('80%')
        .height(50)
        .shaderStyle(this.radialGradientOptions)
      Text('纯色').fontSize(18).width('90%').fontColor(0xCCCCCC)
        .margin({ top: 40, left: 40 })
      Text(this.message)
        .fontSize(50)
        .width('80%')
        .height(50)
        .shaderStyle(this.colorShaderStyle)
    }
  }
}
