Getting started

Trufi Core is the base dependency used to create your public transport app. Have a look at the example implementation that contains further instructions.

Preparing environment

  1. Copy the contents of the folder example into a new repository. See trufi-app for an example because we did it like what described below.

  2. Modify pubspec.yml: Replace the content

        path: ../


          ref: main

    to be able to use this library - trufi-core

  3. Prepare your development environment so you can compile it successfully

Making necessary modifications

  1. Edit main.dart and modify the necessary things

    1. Offline search POI functionality: remove photonUrl and generate your own version of the assets/data/search.json using osm-search-data-export.
    2. Online search POI functionality: remove searchAssetPath

Complementary projects

osm-search-data-export - Generates offline search data that includes POIs, streets and street junctions. The app currently uses the json-compact format.

osm-public-transport-export - Fetches OSM data and generates GeoJSON and additional files.

geojson-to-gtfs - Turns generated GeoJSON and additional data into GTFS.

gtfs-bolivia-cochabamba - Config package that internally uses osm-public-transport-export and geojson-to-gtfs to generate a GTFS file to be used in OTP. Use this as a template to generate your own GTFS.

OpenTripPlanner - Trip planning server that uses GTFS feeds for routing.
