如何添加交互式收藏夹图标

Question

我正在尝试添加一个收藏夹图标，以将该字段发送到另一个页面。

我已经尝试了另一种解决方案，但是没有任何解决方案。 我认为我想要的是可能的，但是如果那不可能，请说

function Mesh(name) {
  this._name = name;
  this.interval = null;
}

Mesh.prototype.blink = function(delay) {
  var Toggle = false
  this.interval = (() => {
    return setInterval(() => {
      console.log(this._name, " blinking ", "Toggle", Toggle)
      Toggle = !Toggle;
    }, delay);
  })();
  console.log("interval in blink:", this.interval)

}

Mesh.prototype.stopBlink = function(duration) {

  setTimeout(() => {
    console.log("interval in stop: ", this.interval)
    clearInterval(this.interval);
  }, duration);
}

let m = new Mesh("mesh")
m.blink(200)
m.stopBlink(1000)

上一页将字段发送到下一页

class ChildItem extends StatelessWidget {
  final String name;
  ChildItem(this.name);
  @override

    return ListTile(

      onTap: () {
        Navigator.push(
          context,
          MaterialPageRoute(
            builder: (context) => ShowData(title: this.name),
          ),
        );
      },
    );
  }
}

我想要的是：那个人按下“收藏夹”图标，然后该字段转到另一页。
