What is causing the following build exception in an existing Flutter project after upgrading flutter to 2.10?

Platform & Project Settings

Next we need to add Android SDK API 31 to our Project Structure under both Platform Settings and Project Settings

• Android Studio > File > Project Structure
• Under Platform Settings click SDKs
• In the middle column click icon button, select "Add Android SDK.."
• You will be prompted to select an Android SDK directory
  • Select your Android Sdk root directory like C:\Android\Sdk
  • do not select the specific API version like C:\Android\Sdk\platforms\android-31. This will be rejected.

• A "Create New Android SDK" window will pop up.
• By default Java SDK 11 & Build target: Android API 31 will be preselected. If not, select them.
• Click OK.

• Android API 31 Platform is now available for your Project.
• Now under Project Settings, click on Project

• On the right under Project SDK:
• Click the dropdown list
• Select Android API 31 Platform
• Click OK

• We're done.

Android 12 SDK API 31 is now installed and ready to compile this project.

You should Set both compileSdkVersion and targetSdkVersion to 31 in your build.gradle(app) file.

android {
    compileSdkVersion 31 // <-- This
    defaultConfig {
        applicationId "com.example.app"
        targetSdkVersion 31 // <-- and this too
        // ...
    }
}
