In this guide, we’ll explore how to create a Hybrid Flutter application using V8JsCore, HTML, CSS, and JavaScript. By combining these technologies, we can build a fluid and dynamic app. Let’s step through the process!

Getting Started

Start by setting up your Flutter environment. Make sure you have Flutter installed and configured correctly on your machine.

Setting Up Your Project

• Open your terminal and create a new Flutter project using the command:

flutter create hybrid_flutter_app

• Navigate to your project folder:

cd hybrid_flutter_app

Creating the HTML Structure

Your HTML file acts like a canvas, where all elements will come together. Here is a basic structure for your HTML page:

    
    


    
        
            
                
                    
                        
                            
                        
                        
                            
                                {{item.title}}
                                {{item.publisher}}
                                {{item.summary.substring(0, 20) + '...'}}
                            
                        
                    
                
            
        
    

Think of this HTML structure like a detailed blueprint for a house. Each element (columns, buttons, images) represents different rooms, all working together to create a user-friendly environment.

Styling with CSS

Now, let’s add some CSS to make our application visually appealing. Here is a simple CSS snippet:

.btn-container {
    margin-top: 10px;
    margin-left: 10px;
    margin-right: 10px;
}
.raised-button {
    color: white;
}
.image-container {
    width: 100px;
    height: 100px;
    padding: 5px;
}
.column-text {
    cross-axis-alignment: start;
}
.text-title {
    font-size: 14px;
    color: black;
}
.text-publisher {
    font-size: 12px;
    color: gray;
}
.text-summary {
    font-size: 12px;
    color: gray;
}

Imagine CSS as the paint and decoration inside your house. It brings personality and style, making it inviting and comfortable for users.

JavaScript Logic

Your JavaScript will handle the dynamic parts of your app, such as fetching data and responding to user input. Below is a simple JavaScript setup for fetching book data:

Page({
    data: {
        list: [],
    },
    onLoad: function (e) {
        cc.setNavigationBarTitle({
            title: 'Python',
        });
        cc.showLoading();
        this.doRequest(true);
    },
    doRequest(isOnload) {
        let that = this;
        cc.request({
            url: 'https://douban.uieee.com/v2/book/search?q=python',
            header: {},
            method: 'GET',
            success: function (response) {
                that.setData({
                    list: response.body.books,
                });
                cc.showToast({
                    title: 'Data loaded',
                });
            },
            fail: function (error) {
                console.log('request error: ' + JSON.stringify(error));
                cc.showToast({
                    title: 'Data loading error',
                });
            },
            complete: function () {
                console.log('request complete');
                if (isOnload) {
                    cc.hideLoading();
                } else {
                    cc.stopPullDownRefresh();
                }
            },
        });
    },
    onItemClick: function (e) {
        var item = this.data.list[e.target.dataset.index];
        cc.navigateTo({
            url: 'detail?item=' + JSON.stringify(item),
        });
    },
    onPullDownRefresh() {
        console.log('onPullDownRefresh');
        this.doRequest(false);
    },
    onUnload() {},
});

In this analogy, JavaScript is your home’s electrical wiring, powering the lights and making things run smoothly.

Troubleshooting Common Issues

If you encounter issues while developing, here are some troubleshooting tips:

• Data Not Loading: Ensure your URL is correct and reachable. Use tools like Postman to test the API.
• Styling Issues: Double-check your CSS selectors and ensure they match the corresponding HTML elements.
• JavaScript Errors: Open your browser’s console (F12) to diagnose JavaScript issues easily.
