flureadium_platform_interface 0.7.0

Platform interface for Flureadium, providing shared models, exceptions, and the abstract FlureadiumPlatform class for EPUB, PDF, and audiobook reading.

Flureadium Platform Interface

A common platform interface for the flureadium plugin.

This interface allows platform-specific implementations of the Flureadium plugin, as well as the plugin itself, to ensure they are implementing the same interface.

Usage

To implement a new platform-specific implementation of flureadium, extend FlureadiumPlatform with an implementation that performs the platform-specific behavior.

This package is endorsed and used by the flureadium package. It should not be used directly by app developers.

Current platform contract

Platform implementations are expected to provide publication lifecycle, visual navigation, playback, preference, decoration, and resource helper APIs. Recent resource helpers include renderFirstPage() for PDF cover generation and extractPageThumbnail() for downscaled JPEG thumbnails from image resources in the currently open publication.

extractPageThumbnail() should return null when a platform cannot resolve or decode the resource. Platforms that do not support thumbnail extraction may keep the default UnimplementedError until they add support.

Note on breaking changes

Strongly prefer non-breaking changes (such as adding a method to the interface) over breaking changes for this package.

See https://flutter.dev/go/platform-interface-breaking-changes for a discussion on why a less-clean interface is preferable to a breaking change.
