Flutter Plugin manifestPlaceholders error

Question

I'm trying to create a plugin for flutter. My problem is that looks like flutter is not recognizing manifestPlaceholders for some reason (probably me doing something wrong).

So I added this lines to my android/build.gradle file.

android {
    compileSdkVersion 28

    defaultConfig {
        minSdkVersion 16
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        manifestPlaceholders = [auth0Domain: "example.auth0.com", auth0Scheme: "demo"] // this one for the manifestPlaceholders replacement.
    }
    ...
}
dependencies {
    implementation 'com.auth0.android:auth0:1.+' // this line to install auth0 dependency
}

But when I try to compile the app I get the following errors:

Attribute data@host at AndroidManifest.xml requires a placeholder substitution but no value for <auth0Domain> is provided.

Attribute data@scheme at AndroidManifest.xml requires a placeholder substitution but no value for <auth0Scheme> is provided.

I really don't know what I'm missing here. Your help will be much appreciated.

Regards

Try adding it to `example/android/app/build.gradle` instead. — Richard Heap, May 14 '19 at 23:51

The placeholder needs to be added to the app's build.grade. In a plugin, that means the example app's - plugin_project/example/android/app/build.grade.

That also means that you should add something to your plugin's readme. Users of your plugin will need to add it to their app project's build.grade. In an app project, that's app_project/android/app/build.grade.
