Mapbox SDK Registry Token is null

I'm experiencing issues installing mapbox_gl plugin on my flutter app...

I did follow the official instrctions from there :

https://pub.dev/packages/mapbox_gl

But whenever I hit flutter run I get the same message :

SDK Registry token is null. See README.md for more information.

Which leads to :

Could not get unknown property 'android' for project ':mapbox_gl' of type org.gradle.api.Project.

Looks like a gradle issue... What am I missing ?

I'm using the beta flutter channel and running with --no-sound-null-safety

Here's my code :

android/build.graddle

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()

        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
        maven {

            authentication {
                basic(BasicAuthentication)
            }
            credentials {
                // Do not change the username below.
                // This should always be `mapbox` (not your username). 
                username = 'mapbox'
                // Use the secret token you stored in gradle.properties as the password
                password = "[Yes I checked this token multiple times]"
            }
        }
    }
}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
    project.evaluationDependsOn(':app')
}

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  # fonts:
  #   - family: Schyler
  #     fonts:
  #       - asset: fonts/Schyler-Regular.ttf
  #       - asset: fonts/Schyler-Italic.ttf
  #         style: italic
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
