Answer 1

Step 1. flutter build apk --debug

Step 2. flutter build apk --profile

Step 3. flutter build apk --release

Answer 2

The only solution that worked for me was downgrading the gradle.build from

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

to

 dependencies {
    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

and changed the gradle-warpper.properties from

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

to

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

Here you can see why you should not just add lintOptions { checkReleaseBuilds false } on the gradle.

Answer 3

I found the workaround I needed for my case, I believe it will work for you as well.

I've set the checkReleaseBuilds flag to false in the android's app-level build.gradle like so:

android {
    ...
    lintOptions {
        checkReleaseBuilds false
    }
}
