步骤：
1、Container不设置宽度，需要设置约束padding；
2、文本使用Flexible形式；

Container(height: 24.dp,padding: EdgeInsetsDirectional.only(start: 8.dp, end: 5.dp),decoration: BoxDecoration(color: Color(0XFFFFFFFF).withOpacity(0.1),borderRadius: BorderRadius.circular(12.dp),),child: Row(mainAxisSize: MainAxisSize.min,crossAxisAlignment: CrossAxisAlignment.center,children: [Container(margin: EdgeInsetsDirectional.only(end: 3.dp),child:  R.img('gift_star_coin.png',width: 16.dp,height: 16.dp,package: ComponentManager.MANAGER_GIFT,),),Flexible(child: Text(_data.totalMoney.toString(),textAlign: TextAlign.center,style: TextStyle(fontSize: 12.0,color: Color(0XFF858585),),),),Container(child: R.img('gift_in_price.png',width: 13.dp,height: 13.dp,package: ComponentManager.MANAGER_GIFT,),),],),),
