Getting the Xcode project to run is pretty easy, but the Android project is a challenge. Fortunately, I’m already a Flutter and Android developer so I had some experience going in. Here were the changes I had to make to the project.
Alway go into Android and gradle sync when you make these changes. Don’t forget to clean the project.
Upgrade the Embedding
In the Android Manifest XML file, change the android name to this: <application
android:name=”${applicationName}”
This makes the embedding compatible with version 2.
Upgrade your gradle version
in build.gradle
classpath ‘com.android.tools.build:gradle:7.2.1’
in grade-wrapper properties
distributionUrl=https\://services.gradle.org/distributions/gradle-7.3.3-all.zip
you mileage may vary, but check these and run sync. Yes, I see that they’re not the same version. When I tried to make the build.gradle line 7.3.3 it broke. Guess it’s the build tool vs the wrapper.
Check your Java SDK
Make sure it’s version 11 of some kind. 16 is coming (or here) so keep an eye on that, but 11 makes it all work currently.
Check your compile SDK version
in build.gradle:
android {
compileSdkVersion 31
your mileage may vary, but check the version against your device or emulator version
Check your Kotlin version
in build.gradle
buildscript {
ext.kotlin_version = ‘1.8.0’

…are ./gradlew clean, flutter clean and flutter pub get.
That’s it!
Let me know in the comments if you hit another problem.
