The problem is that apk built with build flavor does not have flutter_assets, as seen in this screenshot.

Screen Shot 2019-04-11 at 9 29 48 PM

At the moment, my workaround is to run ./gradlew :flutter:copyFlutterAssetsDebug manually whenever I clean the project or make changes, as share in my Hackernoon article.

android.buildTypes.all{ theBuildType ->
    android.productFlavors.all { theProductFlavor ->
        tasks.whenTaskAdded { theTask ->
            if (theTask.name == "merge${theProductFlavor.name.capitalize()}${theBuildType.name.capitalize()}Assets") {
                theTask.dependsOn ":flutter:copyFlutterAssets${theBuildType.name.capitalize()}"
            }
        }
    }
}

I would love to make a PR to fix this, but I'm not familiar with Groovy and Gradle.
