Building the project

Missing Key.Properties file

If you try to build the project straight away, you'll get an error complaining that a file is missing and Exit code 1 from: /GDG-DevFest-App-master/android/gradlew app:properties:. To resolve that,

  1. Open GDG-DevFest-App-master\android\app\build.gradle file and comment following lines-

    //keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
    signingConfigs {
    // release {
    // keyAlias keystoreProperties['keyAlias']
    // keyPassword keystoreProperties['keyPassword']
    // storeFile file(keystoreProperties['storeFile'])
    // storePassword keystoreProperties['storePassword']
    // }
    buildTypes {
    // release {
    // signingConfig signingConfigs.release
    // }
  2. Open GDG-DevFest-App-master\lib\utils\devfest.dart file and customise the texts according to your needs. Eg-

        static const String app_name = “Devfest”;
        static const String app_version = “Version 1.0.4”;
        static const int app_version_code = 1;
        //*  Texts
        static const String welcomeText = “Welcome to GDG DevFest”;
        static const String descText =
            ‘’’DevFests are community-led, developer events hosted by GDG chapters around the globe focused on community building & learning about Google’s technologies. Each DevFest is inspired by and uniquely tailored to the needs of the developer community and region that hosts it.’’’;
        //* ActionTexts
        static const String agenda_text = “Agenda”;
        static const String speakers_text = “Speakers”;
        static const String team_text = “Team”;
        static const String sponsor_text = “Sponsors”;
        static const String faq_text = “FAQ”;
        static const String map_text = “Locate Us”;
  3. Open GDG-DevFest-App-master\lib\home\session.dart file and customise the sessions according to your needs. Eg-

        List<Session> sessions = [
                sessionId: “1”,
                sessionStartTime: “9:00 AM”,
                sessionTotalTime: “30 Mins”,
                sessionTitle: “DevByte: From Zero to ML on Google Cloud Platform”,
                speakerName: “Max Saltonstall”,
                speakerDesc: “Cloud Developer Advocate, Google DevByte speaker”,
                track: "cloud"
  4. Open GDG-DevFest-App-master\lib\home\speaker.dart file and customise the speakers according to your needs. Eg-

        List<Speaker> speakers = [
                speakerName: “Pawan Kumar”,
                speakerDesc: “Google Developer Expert, Flutter”,
                speakerSession: “Talk: Getting Started With Flutter For Web”,
                fbUrl: “”,

                linkedinUrl: “”,
                twitterUrl: “”,
  5. Open GDG-DevFest-App-master\lib\home\team.dart file and customise the teams according to your needs. Eg-

                contribution: “Google CEO”,
  6. Open GDG-DevFest-App-master\lib\map\map_page.dart file and customise the lat long according to your needs. Eg-
