Multidex issue with Flutter:

This is happening because of some reasons: Multidex issue, where it is not enabled or minSdkVersion is not appropriate

Multidex issue with Flutter

Solution

First Make sure your minSdkVersion is 21 or Above that in the app Level Gridle file: [project_folder]/app/build.gradle

defaultConfig {
            // ...
            minSdkVersion 21
            // ...
}

Then, In the same file [project_folder]/app/build.gradle directory and add the following code inside defaultConfig

defaultConfig {
    //...

    multiDexEnabled true
}

Just Add multiDexEnabled true.

And where it sats dependencies add the following code

dependencies {
    //...

    implementation 'com.android.support:multidex:1.0.3'
}

Next: Go to the [project_folder]/android/gradle.properties and add the following 2 lines

android.useAndroidX=true
android.enableJetifier=true

I Hope this quick fix Solves your issue
