Flight CO2 Emissions Calculator

flutter flight co2 calculator

this plugin provides a collection of classes that can be used to:

• load a list of airports from the openflights.org dataset.
• lookup airports matching a search query against the entire data-set of airports.
• calculate the distance and co2 emissions from flights.

what you can do with this

build a flight co2 calculator app such as this:

how to use it

load data:

list<airport> airports = await airportdatareader.load('data/airports.dat');

create an airportlookup service:

final airportlookup = airportlookup(airports: airports);

search for airports matching a query:

list<airport> results = airportlookup.searchstring(query);

calculate distance and co2 emissions:

class flightcalculationdata {
  flightcalculationdata({this.distancekm, this.co2e});
  final double distancekm;
  final double co2e;
}

flightcalculationdata _calculate(flightdetails flightdetails) {
  double distancekm;
  double co2e;
  airport departure = flightdetails.departure;
  airport arrival = flightdetails.arrival;
  if (departure != null && arrival != null) {
    double multiplier =
        flightdetails.flighttype == flighttype.oneway ? 1.0 : 2.0;
    distancekm = distancecalculator.distanceinkmbetween(
        departure.location, arrival.location);
    distancekm = co2calculator.correcteddistancekm(distancekm);
    co2e =
        co2calculator.calculateco2e(distancekm, flightdetails.flightclass) *
            multiplier;
  }
  return flightcalculationdata(distancekm: distancekm, co2e: co2e);
}
