Here is my code

Main.dart

import 'package:flutter/material.dart'; import 'package:clima/screens/loading_screen.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      theme: ThemeData.dark(),
      home: LoadingScreen(),
    );
  }
}

Under the Screens Directory I have 3 files

Under utilites directory there is one file constants1.dart

constants1.dart

import 'package:flutter/material.dart';

  fontSize: 100.0,
);

const kMessageTextStyle = TextStyle(
  fontFamily: 'Spartan MB',
  fontSize: 60.0,
);

const kButtonTextStyle = TextStyle(
  fontSize: 30.0,
  fontFamily: 'Spartan MB',
);

const kConditionTextStyle = TextStyle(
  fontSize: 100.0,
);

Under the services directory i have weather.dart

class WeatherModel {
  String getWeatherIcon(int condition) {
    if (condition < 300) {
      return '🌩';
    } else if (condition < 400) {
      return '🌧';
    } else if (condition < 600) {
      return '☔️';
    } else if (condition < 700) {
      return '☃️';
    } else if (condition < 800) {
      return '🌫';
    } else if (condition == 800) {
      return '☀️';
    } else if (condition <= 804) {
      return '☁️';
    } else {
      return '🤷‍';
    }
  }

  String getMessage(int temp) {
    if (temp > 25) {
      return 'It\'s 🍦 time';
    } else if (temp > 20) {
      return 'Time for shorts and 👕';
    } else if (temp < 10) {
      return 'You\'ll need 🧣 and 🧤';
