All things Flutter


PolyLingual is a new Flutter package that provides internationalisation (multi-language) capabilities for a Flutter app. It does this using a simple JSON file that is embedded into the app. This JSON file can then be updated as required without needing an app rebuild. This is useful for correcting string errors, updating messages or even adding …

Flutter Device Locale

This is a follow up project created for the Watch Tips app demo that was created and released into the app store. Basically the app displays a generic currency value and formats it in a ‘UK’ standardised way with no currency symbol. This was OK, but if the device is used elsewhere then the currency …

Flutter and Apple Watch

SliverImage Widget

The repo for the SliverImage demo shows a way of adding an image to the top of a ScrollView in Flutter that will collapse as the list is scrolled up.  This has been created as a separate widget so that it can be used and embedded easily in various projects.

Flutter SWAPI

We have put up a complete Flutter app on Github that is a demo of accessing a third party REST API and converting and using the resulting JSON to build various lists.
