Flutter unity 3D widget for embedding unity in flutter. Add a Flutter widget to show unity. Works on Android, iOS in works.
First depend on the library by adding this to your packages pubspec.yaml:
dependencies:
flutter_unity_widget: ^0.1.3+2Now inside your Dart code you can import it.
import 'package:flutter_unity_widget/flutter_unity_widget.dart';
For this, there is also a video tutorial, which you can find a here.
- Create an unity project, Example: 'UnityDemoApp'.
- Create a folder named
unityin flutter project folder. - Move unity project folder to
unityfolder.
Now your project files should look like this.
.
├── android
├── ios
├── lib
├── test
├── unity
│ └── <Your Unity Project> // Example: UnityDemoApp
├── pubspec.yml
├── README.md
-
First Open Unity Project.
-
Click Menu: File => Build Settings => Player Settings
-
Change
Product Nameto Name of the Xcode project, You can find it followios/${XcodeProjectName}.xcodeproj.Android Platform:
-
Change
Scripting Backendto IL2CPP. -
Mark the following
Target Architectures:- ARMv7 ✅
- ARM64 ✅
- x86 ✅
IOS Platform:
- Other Settings find the Rendering part, uncheck the
Auto Graphics APIand select onlyOpenGLES2. - Depending on where you want to test or run your app, (simulator or physical device), you should select the appropriate SDK on
Target SDK.
-
Copy Build.cs and XCodePostBuild.cs to unity/<Your Unity Project>/Assets/Scripts/Editor/
Open your unity project in Unity Editor. Now you can export unity project with Flutter/Export Android or Flutter/Export IOS menu.
Android will export unity project to android/UnityExport.
IOS will export unity project to ios/UnityExport.
Android Platform Only
- After exporting the unity game, open Android Studio and and add the
Unity ClassesJava.jarfile as a module to the unity project. You just need to do this once if you are exporting from the same version of Unity everytime. The.jarfile is located in the<Your Flutter Project>/android/UnityExport/libfolder - Next open
build.gradleofflutter_unity_widgetmodule and replace the dependencies with
dependencies {
implementation project(':UnityExport') // The exported unity project
implementation project(':unity-classes') // the unity classes module you added from step 1
}- Next open
build.gradleofUnityExportmodule and replace the dependencies with
dependencies {
implementation project(':unity-classes') // the unity classes module you added from step 1
}- Next open
build.gradleofUnityExportmodule and remove these
bundle {
language {
enableSplit = false
}
density {
enableSplit = false
}
abi {
enableSplit = true
}
}Copy UnityMessageManager.cs to your unity project.
Copy this folder JsonDotNet to your unity project.
Copy link.xml to your unity project.
