It's very simple and Calibre makes it much less painful. Just add the following lines as Extra CSS to Calibre and then convert whatever Chinese text to ePub. This works for both traditional and simplified Chinese.
<@font-face {
font-family: "Arial", "SimSun", "Times New Roman", "MingLiU", "PMingLiU", "Cambria", "Consolas", "DroidFont", serif, sans-serif;
font-weight: normal;
font-style: normal;
src: url('res:///system/fonts/DroidSansFallback.ttf');
}
@font-face {
font-family: "Arial", "SimSun", "Times New Roman", "MingLiU", "PMingLiU", "Cambria", "Consolas", "DroidFont", serif, sans-serif;
font-weight: bold;
font-style: normal;
src: url('res:///system/fonts/DroidSansFallback.ttf');
}
@font-face {

Have fun of reading Chinese ePub!
I try your method, the ePub still show square, what other steps I need to do before it will show chinese.
I figure it out, I need to turn on the Publisher default under text.

Where did you get your ePub files from? The easiest way is to convert your ePub to ePub again with Calibre.
For example the Chinese ePub downloaded from Gutenberg site is not readable on Nook Tablet straight off Gutenberg. After conversion with the Extra CSS setting in Calibre all the 'blocks' are turned into Chinese characters.

You can run the if/show command to control the display of a pop-up window based on the stack component and the position:fixed CSS file. The following code implements two custom pop-up windows:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
1. Initialize data models.
data() {
return {

toast() {
prompt.showToast({
message: 'View privacy agreement'
})
}
How can I read the global variables defined in app.ux from a JavaScript file?
For example, You can define the variable AppData in app.ux.
data: {
AppData: '123456',
}
The code in the JavaScript file is as follows:
export default {
getAppData() {
return getApp().$def.data.AppData
}
}
For more information, please refer to the Common methods section in Script.
The promt.showDialog API of Quick App can be used to implement simple pop-up elements such as text and buttons, but cannot achieve complex display effects. UI designers will often design complex effects, so how do we actually achieve them as engineers?
For example, the design of a pop-up includes a list, in which images are displayed on the left and descriptions need to be shown on the right, as shown in Figure 1 below. Another pop-up instructs users to check the app’s privacy statement via a link, as shown in Figure 2.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Figure 1 Pop-up with a list Figure 2 Pop-up with a link
Proper arrangement of quick app elements and style attributes can help achieve such complex effects.
SolutionYou can use the stack element with the position: fixed CSS style to implement a custom pop-up. Whether to display the pop-up can be determined using the if/show command. Sample code is as follows:
1.Initialize data models:
HTML:
data() {
return {
list: [1, 2, 3],
isShow: false,
ifShow1: false,
ifShow2: false
}
},
2.Page layout:
HTML:
<text onclick="showToast1">Custom pop-up window 1</text>
<text onclick="showToast2">Custom pop-up window 2</text>
<!-- Pop-up window -->
<div if="{{isShow}}" class="modal center-modal">

Sorry. It supported in quick app. It is different from Xamarin. If you want to implement custom pop up in xamarin, you can try to study other tutorials perhaps.
Hope it works for Hormony os as well.

Introduction
In this article, we will be integrating Huawei Account, Push kit and Analytics kit in Flutter DietApp. In this article we can see on filling form diet plan i.e. what kind of food you can have to gain/loose the weight with images, we can see in the Diet screen. Flutter plugin provides simple and convenient way to experience authorization of users. Flutter Account Plugin allows users to connect to the Huawei ecosystem using their Huawei IDs from the different devices such as mobiles phones and tablets, added users can login quickly and conveniently sign in to apps with their Huawei IDs after granting initial access permission.
Huawei Push kit is a messaging service provided for you. It establishes a messaging channel from the cloud to devices. By integrating Push Kit, you can send messages to your apps on user’s devices in real time. This helps you to maintain closer ties with users and increases user awareness and engagement with your apps.
Huawei Analytics is a one-stop solution to get user behavior analysis in different platforms for all yours products such as mobile apps, web apps and quick apps. It helps developers to get detailed analysis report and also provides crash reports by default. It offers scenario-specific data collection, management, analysis, and usage, helping enterprises to achieve effective user acquisition, product optimization, precise operations, and business growth.

Conclusion
In this article, we have learnt how to integrate Huawei Account kit, Push kit and Analytics kit in Flutter DietApp. Once Account kit integrated, users can login quickly and conveniently sign in to apps with their Huawei IDs after granting initial access permission. Push kit enables you to send push notification to user device in real time, you can see the push notification in the result part.
Thank you so much for reading. I hope this article helps you to understand the integration of Huawei Account kit, Push kit and Analytics kit in flutter DietApp.

Introduction
In this article, we will be integrating Huawei Account, Push kit and Analytics kit in Flutter DietApp. Here we can see on filling form diet plan i.e. what kind of food you can have to gain/loose the weight with images, we can see in the diet screen with paid diet plan. Flutter plugin provides simple and convenient way to experience authorization of users. Flutter Account Plugin allows users to connect to the Huawei ecosystem using their Huawei IDs from the different devices such as mobiles phones and tablets, added users can login quickly and conveniently sign in to apps with their Huawei IDs after granting initial access permission.
Huawei Push kit is a messaging service provided for you. It establishes a messaging channel from the cloud to devices. By integrating Push Kit, you can send messages to your apps on user’s devices in real time. This helps you to maintain closer ties with users and increases user awareness and engagement with your apps.
Huawei Analytics is a one-stop solution to get user behavior analysis in different platforms for all yours products such as mobile apps, web apps and quick apps. It helps developers to get detailed analysis report and also provides crash reports by default. It offers scenario-specific data collection, management, analysis, and usage, helping enterprises to achieve effective user acquisition, product optimization, precise operations, and business growth.
We will also learn to integrate Huawei Crash Service in this application. It is a responsibility of the developer to build crash free i.e. unexpected exit of application, it is very difficult to find the cause of the crash in huge application code base. This unexpected crash makes app users annoying and may lead to business loss and reduce market value of the product and the company. To avoid such crashes Huawei provides Crash service which makes developer to find the crash and cause of unexpected exit of the application in AG-console. Crash SDK provides very simple and developer need not code much to implementation crash service. You can also download the detailed crash report whenever required.

Development Overview
You need to install Flutter and Dart plugin in IDE and I assume that you have prior knowledge about the Flutter and Dart.
Hardware Requirements
A computer (desktop or laptop) running Windows 10.
Android phone (with the USB cable), which is used for debugging.
Software Requirements
Java JDK 1.7 or later.
Android studio software or Visual Studio or Code installed.
HMS Core (APK) 4.X or later.
Integration process
Step 1: Create Flutter project.
Step 2: Add the App level gradle dependencies. Choose inside project Android > app > build.gradle.
apply plugin: 'com.android.application'
apply plugin: 'com.huawei.agconnect'
Root level gradle dependencies
maven {url 'https://developer.huawei.com/repo/'}
classpath 'com.huawei.agconnect:agcp:1.5.2.300'
Step 3: Add the below permissions in Android Manifest file.
<uses-permission android:name="android.permission.INTERNET" />
Step 4: Download flutter push kit plugins
Step 5: Add downloaded file into parent directory of the project. Declare plugin path in pubspec.yaml file under dependencies.
Add path location for asset image.
