    Flex({ 
      justifyContent:FlexAlign.SpaceBetween, 
      alignContent: FlexAlign.Center 
    }) { 
      Text(this.message) 
        .flexShrink(1) 
        .fontSize(17) 
        .fontWeight(FontWeight.Bold) 
        .backgroundColor(Color.Yellow) 
        .maxLines(1) 
        .textOverflow({overflow: TextOverflow.Ellipsis}) 
      //.wordBreak(WordBreak.BREAK_ALL) 
      Text(this.message1) 
        .flexShrink(0) 
        .fontSize('14') 
        .maxLines(1) 
        .backgroundColor(Color.Grey) 
        .textAlign(TextAlign.End) 
    }.backgroundColor("#EBEBEB") 
    .width("90%") 
    .height('100%')
