Cards not rendering when flutter web is deployed to a server (netlify)

问题

I made a flutter app as my portfolio and Built it for web using canvaskit renderer using flutter build web --web-renderer canvaskit

The project runs perfectly fine when running on localhost debug mode.

I have made a custom widget HoverConatiner which contains card inside a container

import 'package:flutter/material.dart';
import 'package:awesome_icons/awesome_icons.dart';
import 'package:url_launcher/url_launcher_string.dart';

class HoverContainer extends StatefulWidget {
  final double width;
  final double height;
  final String imagePath;
  final String gitLink;
  final String link;
  final String title;

  const HoverContainer({
    required this.width,
    required this.height,
    required this.imagePath,
    required this.gitLink,
    required this.link,
    required this.title,
    super.key,
  });

  @override
  _HoverContainerState createState() => _HoverContainerState();
}

class _HoverContainerState extends State<HoverContainer> {
  bool _isHovering = false;

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTap: () {
        setState(() {
          _isHovering = true;
        });
      },
      onDoubleTap: () {
        setState(() {
          _isHovering = false;
        });
      },
      child: MouseRegion(
        onEnter: (event) {
          setState(() {
            _isHovering = true;
          });
        },
        onExit: (event) {
          setState(() {
            _isHovering = false;
          });
        },
        child: AnimatedContainer(
          padding: const EdgeInsets.all(20),
          duration: const Duration(milliseconds: 200),
          width: _isHovering ? widget.width * 1.1 : widget.width,
          height: _isHovering ? widget.height * 1.1 : widget.height,
          child: Card(

This is deployed on link

Below is the expected output when running on localhost ....

Flutter web部署到服务器（netlify）时，卡片未渲染。

If in case you are wondering why I am not using html renderer, because when I tried html renderer the Linier gradient text was also not showing along with the cards.

Github Link of Flutter project - Click
Github Link of Build/web with canvaskit - Click

Thanks in advance!

I tried with both canvaskit and html renderer but both failed to render the cards as expected, I have already attached image of expected output.
