๐Ÿฎ Fudge: Jetpack Compose TV UI Kit ๐ŸŽฌ

Fudge is a ๐ŸŒŸ Jetpack Compose library module designed to make the development of TV interfaces and applications smoother and sweeter. Tailored specifically for the unique needs of TV UIs, Fudge offers a collection of pre-built components and tools that help you create immersive and user-friendly experiences on large screens.

Features ๐ŸŽ‰

  • Pre-defined Components: Fudge provides a range of ready-to-use components optimized for TV, including focusable buttons, lists, and custom navigation drawers, ensuring your app looks and performs beautifully on the big screen.
  • Focus Management: Built with TV in mind, Fudge simplifies focus handling and navigation, making it easier to manage remote control interactions.
  • State Management: Supports advanced screen state management by implementing patterns like MVI (Model-View-Intent) or MVVM (Model-View-ViewModel), delivering fluid and responsive UIs.
  • Customization: Fudge components are highly customizable, allowing you to adapt them to match the unique style and branding of your TV application.
  • Jetpack Compose Compatibility: Fully integrated with Jetpack Compose, the modern Android UI framework, ensuring a seamless and efficient development experience tailored for TV platforms.

Model-View-Intent (MVI) Architecture ๐Ÿ—๏ธ

Fudge encourages the use of the Model-View-Intent (MVI) architecture pattern for effective screen state management. In this pattern:

  • Model: Represents the state of the UI. Fudge provides a FudgeTvViewModel class that extends from ViewModel and handles the UI state.
  • View: Renders the UI based on the state provided by the ViewModel. Fudge components are seamlessly integrated with Compose to create a declarative UI.
  • Intent: Represents user actions or events that trigger state changes. Fudge's components, like buttons and text fields, are designed to emit these intents efficiently.

This setup leverages Fudge's components and ViewModel to accelerate the development of robust features while adhering to best practices in architecture and UI design.

Here's an example of how you can use FudgeTv components in a screen following the MVI pattern:

@Composable
fun SignInScreen(
    viewModel: SignInViewModel = hiltViewModel(),
    onGoToHome: () -> Unit,
    onGoToProfiles: () -> Unit,
    onGoToSignUp: () -> Unit,
    onBackPressed: () -> Unit,
) {
    FudgeTvScreen(
        viewModel = viewModel,
        onBackPressed = onBackPressed,
        onInitialUiState = { SignInUiState() },
        onSideEffect = {
            when(it) {
                SignInSideEffects.AuthenticationSuccessfully -> onGoToHome()
                SignInSideEffects.ProfileSelectionRequired -> onGoToProfiles()
                SignInSideEffects.CreateNewAccount -> onGoToSignUp()
            }
        }
    ) { uiState ->
        SignInScreenContent(
            uiState = uiState,
            actionListener = viewModel
        )
    }
}

Inside the SignInScreen function, there's a FudgeTvScreen composable. This is a custom screen component provided by the FudgeTV library. It's responsible for managing the UI state and handling side effects in a declarative way. Here's what each parameter does:

  • viewModel: The SignInViewModel instance passed to the FudgeTvScreen component.
  • onBackPressed: The lambda function passed to the FudgeTvScreen component, which is called when the user navigates back from the screen.
  • onInitialUiState: A lambda function that provides the initial UI state for the screen. In this case, it returns a new instance of SignInUiState.
  • onSideEffect: A lambda function that handles side effects triggered by the ViewModel. When a side effect occurs (such as successful authentication or profile selection required), this function is called, and appropriate actions (navigating to home or profile selection) are performed.

Finally, inside the FudgeTvScreen composable, there's another composable function called SignInScreenContent. This is the actual content of the sign-in screen, where UI elements like text fields, buttons, etc., are defined. It takes the current UI state (uiState) as a parameter and callback functions for handling user interactions:

  • uiState: The current state of the sign-in screen, which is provided by the FudgeTvScreen component.
  • onEmailChanged: A callback function for handling changes in the email input field.
  • onPasswordChanged: A callback function for handling changes in the password input field.
  • onSignIn: A callback function for handling the sign-in action.

Overall, this implementation follows a declarative approach using Compose and Fudge components, making it easier to manage the UI state and handle user interactions in a clear and concise manner.

@Composable
internal fun SignInScreenContent(
    uiState: SignInUiState,
    actionListener: SignInScreenActionListener
) {
    FudgeTvScreenContent(
        error = uiState.errorMessage,
        onErrorAccepted = actionListener::onErrorMessageCleared
    ) {
        SignInDialog(uiState = uiState)
        SignInVideoBackground()
        SignInLogo()
        Column(
            modifier = Modifier
                .fillMaxHeight()
                .fillMaxWidth(0.9f),
            verticalArrangement = Arrangement.Center,
        ) {
            SignInMainContent(
                uiState = uiState,
                onEmailChanged = actionListener::onEmailChanged,
                onPasswordChanged = actionListener::onPasswordChanged,
                onSigInPressed = actionListener::onSigInPressed
            )
            SignInSecondaryContent(onGoToSignUp = actionListener::onGoToSignUp)
        }
    }
}

This is a Composable function named SignInScreenContent, responsible for rendering the content of the sign-in screen. It takes the following parameters:

  • uiState: The current state of the sign-in screen, containing properties like isLoading, email, and password.
  • onEmailChanged: A callback function that will be invoked when the email input field changes.
  • onPasswordChanged: A callback function that will be invoked when the password input field changes.
  • onSignIn: A callback function that will be invoked when the user clicks the sign-in button.

The FudgeTvScreenContent composable is used to create a screen layout. It takes a title resource as a parameter.

Overall, the SignInScreenContent composable is responsible for rendering the content of the sign-in screen using Fudge's components. It ensures a consistent UI design and handles user interactions efficiently through callback functions.

Using FudgeTV UI Library

Step 1: Configuring Maven Repository

Ensure to add the GitHub Maven repository to your build.gradle or settings.gradle file to access the dependency hosted on GitHub Packages:

repositories {
    maven {
        url = uri("https://maven.pkg.github.com/sergio11/fudge_tv_compose_library")
        credentials {
            // Here, set your authentication credentials
            username = githubProperties["gpr.usr"] as String? ?: System.getenv("GPR_USER")
            password = githubProperties["gpr.key"] as String? ?: System.getenv("GPR_API_KEY")
        }
    }
}

Step 2: Adding the Dependency to the Project

Once the repository is configured, you can add the "Fudge: Jetpack Compose TV UI Kit" dependency to your project.

fudge-tv-compose = "CURRENT_VERSION"
fudge-tv-compose = { module = "com.dreamsoftware.libraries:fudge-tv-compose", version.ref = "fudge-tv-compose" }
implementation(libs.fudge.tv.compose)
