✨ (2024-04-22) Decode and encode GeoJSON, WKT and WKB in Dart and Flutter apps
🧭 The geospatial code repository with geospatial data structures, tools and utilities for Dart and Flutter - coordinates, geometries, feature objects, metadata, spherical geodesy, projections, tiling schemes, vector data models and formats, and geospatial Web APIs.
📦 The code packages published at pub.dev:
| Code | Package | Description |
|---|---|---|
| 🌐 geobase |  |
Geospatial data structures (coordinates, geometries, features, metadata), spherical geodesy, projections and tiling schemes. Vector data format support for GeoJSON, WKT and WKB. |
| 🌎 geodata |  |
Geospatial feature service Web APIs with support for GeoJSON and OGC API Features clients. |
🧩 See milestones and open issues for planned features, requests for change, and observed bugs.
✨ See also the Geospatial demos for Dart code repository for demo and sample apps demonstrating the usage of geobase and geodata along with other topics.
| Code | Description |
|---|---|
| earthquake_map | Shows earthquakes fetched from the USGS web service on a basic map view. The demo uses both geobase and geodata packages for geospatial data accesss. Discusses also state management based on Riverpod. The map UI is based on the Google Maps Flutter plugin. |
📅 The first version of this repository was published in August 2022, updated October 2023.
Some code samples (Last updated: Feb 2020) also, code at GitHub:
| Code | Demo | Description |
|---|---|---|
| quake | - | A gRPC service for monitoring earthquakes based on data provided by the USGS. |
| quake_monitor | demo | Flutter app, deployed to web, to monitor earthquakes with two backend service integrations choices (RESTful API and a gRPC service). |
