Geospatial data structures, tools and utilities for Dart and Flutter mobile developers.

🧭 Geospatial toolkit for Dart

Geospatial data structures, tools and utilities for Dart and Flutter mobile developers. Contains also some non-geospatial library packages.

Packages and documentation are published at pub.dev.

Latest package releases:

Package @ pub.dev	Version	Documentation	Example code
🗒️ attributes		API reference	Example
☁️ datatools		API reference
🌐 geocore		API reference	Example
🌎 geodata		API reference	Example

All packages supports Dart null-safety and using them requires the latest SDK from a beta channel. However your package using them doesn't have to be migrated to null-safety yet.

Please see the official null-safety migration guide how to switch to the latest beta release of Dart or Flutter SDKs.

Code

This repository is at the alpha-stage, breaking changes are possible.

This repository contains the following Dart code packages:

Code @ GitHub	SDK	Description
🗒️ attributes	Dart	Data structures and utilities for identifiers, value maps and dynamic data objects.
☁️ datatools	Dart	Metadata structures and utilities to access Web APIs.
🌐 geocore	Dart	Geospatial data structures (features, geometry and metadata) and utilities (GeoJSON parser).
🌎 geodata	Dart	A geospatial client reading OGC API and other data sources.
