-- Get.put e Get.putAsync seguem a mesma ordem de criação, com a diferença que o Async opta por aplicar um método assíncrono: Esses dois métodos criam e já inicializam a instância. Esta é inserida diretamente na memória, através do método interno `insert` com os parâmetros `permanent: false` e `isSingleton: true` (esse parâmetro `isSingleton` serve apenas para dizer se é para utilizar a dependência colocada em `dependency`, ou se é para usar a dependência colocada no `FcBuilderFunc`). Depois disso, é chamado o `Get.find` que imediatamente inicializa as instâncias que estão na memória.

 - Get.create: Como o nome indica, você vai "criar" a sua dependência! Similar ao `Get.put`, ela também chama o método interno `insert` para instanciamento. Contudo, `permanent` e `isSingleton` passam a ser `true` e `false` (Como estamos "criando" a nossa dependência, não tem como ela ser um Singleton de algo, logo, `false`). E por ser `permanent: true`, temos por padrão o benefício de não se perder entre telas! Além disso, não é chamado o `Get.find`, logo ela fica esperando ser chamada para ser usada. Ele é criado dessa forma para aproveitar o uso do parâmetro `permanent`, já que, vale ressaltar, o Get.create foi criado com o objetivo de criar instâncias não compartilhadas, mas que não se perdem, como por exemplo um botão em um listView, que você quer uma instância única para aquela lista - por conta disso, o Get.create deve ser usado em conjunto com o GetWidget.
