The embed package enables developers to embed arbitrary file content directly into Dart code through code generation. This is particularly useful for including assets like images, JSON files, or configuration data without relying on the standard asset bundle system. By generating Dart constants from file contents at compile time, it improves performance and simplifies access to embedded resources. The package supports multiple platforms, including Android, iOS, macOS, Windows, and Linux, making it ideal for cross-platform applications that require efficient, static resource handling.
Use cases
- Embedding configuration files
- Including static assets in app binaries
- Reducing runtime asset loading
- Simplifying local file access in Flutter apps
- Optimizing startup performance
Key features
- Code generation for file embedding
- Supports multiple file types
- Cross-platform compatibility
- Compile-time resource inclusion
- Minimal runtime overhead
Suitable for
- Flutter apps needing embedded assets
- Performance-critical applications
- Apps with static configuration data
- Developers avoiding asset bundles
- Projects requiring zero-runtime file I/O
Considerations
- Requires code generation step
- Not suitable for dynamic or frequently changing files
- May increase build time
- Limited to compile-time file content
- File paths must be known at build time
