如何在颤振中将液体滑动动画添加到主页中？

Question

1. 我正在尝试在 Flutter 中添加 Liquid Swipe 以进行介绍 Slide it Works Fine
2. 它工作正常，但循环无法移动到主页
3. 我尝试添加 Navigator.push() 它不起作用
4. 我的包裹liquid_swipe 2.1.0
5. 我需要导航到我的 Header() 页面
6. 当我单击“跳过”时，它会转到主页(Header())
7. 列表项
8. 提前致谢
9. v2.0.0 迁移到空安全。

我的代码是：

import 'dart:math';

import 'package:abcde/widgets/headers.dart';
import 'package:flutter/material.dart';
import 'package:liquid_swipe/liquid_swipe.dart';

void main() {
  /// Comment or uncomment to run both examples
  runApp(
    WithBuilder(),
    //WithPages()
  );
}

///Class to hold data for itembuilder in Withbuilder app.
class ItemData {
  final Color color;
  final String image;
  final String text1;
  final String text2;
  final String text3;

  ItemData(this.color, this.image, this.text1, this.text2, this.text3);
}

/// Example of LiquidSwipe with itemBuilder
class WithBuilder extends StatefulWidget {
  @override
  _WithBuilder createState() => _WithBuilder();
}

class _WithBuilder extends State<WithBuilder> {
  int page = 0;
  late LiquidController liquidController;
  late UpdateType updateType;

  List<ItemData> data = [
    ItemData(
        Colors.blue, 'assets/images/img/gs.jpg', "Hi", "It's Me", "Sahdeep"),
    ItemData(Colors.deepPurpleAccent, 'assets/images/img/gs.jpg', "Take a",
        "Look At", "Liquid Swipe"),
  
  ];
  @override
  void initState() {
    liquidController = LiquidController();
    super.initState();
  }

  Widget _buildDot(int index) {
    double selectedness = Curves.easeOut.transform(
      max(
        0.0,
        1.0 - ((page) - index).abs(),
      ),
    );
    double zoom = 1.0 + (2.0 - 1.0) * selectedness;
    return new Container(
      width: 25.0,
      child: new Center(
        child: new Material(

          type: MaterialType.circle,
          child: new Container(
            width: 8.0 * zoom,
