HarmonyOS 鸿蒙Next TextInput可以设置默认输入法吗？

@Entry
@Component
struct TextInputTest {
  @State message: string = 'Hello World';
  build() {
    Row() {
      Column() {
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
        Button("获取焦点").onClick(()=>{
          focusControl.requestFocus("DemoInput")
        })
        TextInput({placeholder:'焦点测试'})
          .key("DemoInput")
          .type(InputType.Number)
          .inputFilter('[a-z,0-9]', (e) => {
            console.log(JSON.stringify(e))
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
