Welcome to the world of UIWidgets, the powerful plugin package designed to streamline app development in Unity! This guide is your go-to resource for understanding how to create, debug, and deploy cross-platform applications using this innovative tool. Whether you’re a seasoned developer or just getting started, we will walk you through the essential steps while providing troubleshooting tips along the way.

Understanding UIWidgets

Imagine you are an architect—a building designed using one framework, and now you have the opportunity to use a new one that makes your structures stronger and smarter. UIWidgets acts like that new architectural framework, offering enhanced features that allow developers to create more sophisticated and efficient apps. UIWidgets 2.0 is developed specifically for the Unity China version, optimized to provide about a 10% performance gain on mobile devices.

Setting Up UIWidgets 2.0

• Unity Compatibility: Ensure you’re using the correct Unity version. UIWidgets 2.0 is only compatible with the Unity China version.
• Download the Package: Obtain the latest UIWidgets package from GitHub.
• Install Git LFS: Since UIWidgets 2.0 has large files, you’ll need to install Git Large File Storage to pull these libraries successfully.

Creating Your First UIWidgets App

To get you started on creating a simple UIWidgets app, follow the steps below:

1. Open Unity: Start a new Unity project with the Unity Editor.
2. Create a Scene: Go to File > New Scene. Add a UI Canvas using GameObject > UI > Canvas.
3. Add Widgets: Create a new C# script named UIWidgetsExample.cs and paste the following code:

using System.Collections.Generic;
using uiwidgets;
using Unity.UIWidgets.cupertino;
using Unity.UIWidgets.engine;
using Unity.UIWidgets.ui;
using Unity.UIWidgets.widgets;
using Text = Unity.UIWidgets.widgets.Text;
using ui_ = Unity.UIWidgets.widgets.ui_;
using TextStyle = Unity.UIWidgets.painting.TextStyle;

namespace UIWidgetsSample {
    public class UIWidgetsExample : UIWidgetsPanel {
        protected void OnEnable() {
            if (true) {
                AddFont(Material Icons, new List { "MaterialIcons-Regular.ttf" }, new List { 0 });
            }
            base.OnEnable();
        }

        protected override void main() {
            ui_.runApp(new MyApp());
        }

        class MyApp : StatelessWidget {
            public override Widget build(BuildContext context) {
                return new CupertinoApp(home: new CounterApp());
            }

            internal class CounterApp : StatefulWidget {
                public override State createState() {
                    return new CountDemoState();
                }

                internal class CountDemoState : State {
                    private int count = 0;
                    public override Widget build(BuildContext context) {
                        return new Container(
                            color: Color.fromARGB(255, 255, 0, 0),
                            child: new Column(children: new ListWidget {
                                new Text($"count: {count}", style: new TextStyle(color: Color.fromARGB(255, 0, 0, 255))),
                                new CupertinoButton(
                                    onPressed: () => setState(() => count++),
                                    child: new Container(color: Color.fromARGB(255, 0, 255, 0), width: 100, height: 40)
                                )
                            })
                        );
                    }
                }
            }
        }
    }

4. Save your script and attach it to the Panel you created earlier.
5. Finally, press the Play button to test your app!

Building the App

Now that your app is up and running, you can package it for various platforms:

1. Open the Build Settings from File > Build Settings…
2. Select your target platform and click on Build.

Troubleshooting Tips

Should you encounter any issues, here are some helpful troubleshooting ideas:

• Editor Crashes: Make sure you are using compatible Unity versions. For example, UIWidgets 2.0.3 works with Unity China version between 2019.4.26f1c1 and 2019.4.29f1c1.
• DllNotFoundException: Ensure that the native libraries are downloaded correctly to your project; you may need to run git lfs pull.
• Rendering Issues: If there are discrepancies between your expectations and the app’s performance, verify UIWidgets and Unity compatibility as mentioned earlier.
