 ┃ ┣ 📂main
 ┃ ┃ ┣ 📂graphql
 ┃ ┃ ┃ ┣ 📂queries
 ┃ ┃ ┃ ┃ ┗ 📜quotes.graphql

Model

• Given a GraphQL schema and query definition, the Apollo Kotlin plugin defines a Gradle task named generateApolloSources to generate the models

View

• Fetches all quotes via Apollo client and sends them to the ViewModel
• Controls the application's display of the quotes and interaction with the user through the button
• Triggers and subscribes to the ViewModel's LiveData updates

ViewModel

• Updates the MutableLiveData with a random quote
