App philosophy

In short, I first made this app only for myself because I wasn’t happy with any app that already exists. All I needed was a simple, clutter-free interface to show bus timings of only the buses I’m actually taking. On rare occasions, I wounldn’t know where the bus stop is. I’d just use Google Maps. I never found large maps on bus apps useful.

No map

The thing is, once you know where a bus stop is, you won’t need to use the map again. If you already know where the stop is, the mpa on your scren takes more space. There are rare occasions when I don’t know how to get to the bus stop, but that’s why I have Google/Apple Maps.

Clutter free interface

You need bus timings. I’m giving you bus timings. Period.

Context-aware favorites

  • You saved Bus 14 at Bedok Interchange as a favorite.
  • You open the app near Bedok Interchange
  • We assume that you are taking Bus 14, so we put its timings at the top of the screen (refer to the images above)

Other information

Built setup

Your system requires the Flutter SDK. Follow the steps here to install it on your system. Once Flutter is installed, follow these steps:

  1. Clone or fork this repository.
  2. In the lib folder, create keys.dart .

In keys.dart , paste the following:

final String apiKey = '<LTA API KEY>';

To get an API key, go to LTA’s Request For API Access web page and fill out the form. The key is required for the app to work properly.

Once the key as been set up, the app can be tested with the following commands:

flutter run

Please check out the wiki for additional information.

Generating icons and splash screens

After updating pubspec.yaml , run these commands:

flutter pub run flutter_launcher_icons:main
flutter pub pub run flutter_native_splash:create

Stuck at installing debug Android app?

Go to app settings and uninstall your app. The app may not appear in your launcher, but it could still be installed. Go to your settings, find it, and completely uninstall it.

This can also be done using ADB:

adb uninstall com.themindstorm.nextbussg

If this does not work, check out this answer on SO.

Build Android APK and appbundle

flutter build appbundle
flutter build apk

Once the APK has been built, install it on a physcally connected Android device:

flutter install

If you have multiple devices, you can view a list of Android devices connected using this command:

adb devices

And to install the app on an Android device, copy the device ID and install the app using

flutter install <devce ID>
