Try changing the abiFilters in build.gradle at android/app/build

See documentation for abiFilters.

defaultConfig { 
    ndk { 
        abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', 'mips', 'mips64', 'arm64-v8a' 
    }
}

Only platforms specified in the abiFilters are built. If you are building for a local emulator on an x86 computer, you will need 'x86', 'x86_64'.

Common issue: excluding 'x86', 'x86_64' to prevent your app from being available to x86 android devices in the Play Store or bots, then being unable to run your app on your local emulator, while a physically connected android device builds fine.

add ndk abiFilters in android/app/build.gradle

defaultConfig {
        applicationId "com.devsig.cloudauthenticator"
        minSdkVersion 21
        targetSdk 32
        versionCode 4
        versionName "1.0.4"
        multiDexEnabled true
        signingConfig signingConfigs.debug
        ndk {
            abiFilters "armeabi", "x86", "armeabi-v7a", "x86_64", "mips",
                    "mips64", "arm64-v8a"
        }
    }

In my case I solved this by running 'flutter upgrade' from the command line.
