| Your application is not ready when this file is loaded by the framework.

| You must import them inside the life-cycle methods defined inside
| the provider class.

| @example:
|
| public async ready () {
|   const Database = this.app.container.resolveBinding('Adonis/Lucid/Database')
|   const Event = this.app.container.resolveBinding('Adonis/Core/Event')
|   Event.on('db:query', Database.prettyPrint)
