Query external DynamoDB table from Flutter using AWS Amplify
AWS Amplify makes the job of authenticating a Flutter App very simple. As we mentioned in our previous post, following the quickstart document for authentication is relatively straightforward. Unfortunately the documentation for connecting to an Existing AWS DynamoDB table is slightly harder to follow as it is incomplete, and none of the examples show how…
Using AWS Amplify to authenticate a Flutter App
I recently needed to create a new app which requires user authentication and a data backend. Rather than build this for scratch I decided to use an existing authentication provider. Firebase or Amplify? There are two main contenders for this, Google’s Firebase and Amazon AWS. I did a bit of reading around. The general consensus…
Building an Audio Player in Flutter with Just Audio
I recently needed to create a reusable Audio Player for a Flutter App I was working on. After a bit of research I decided to use the Just Audio plugin. As is often the case I found that the documentation was useful for standalone implementations, but not entirely helpful for reusability. The first step is…
Styling Tab Bar in Flutter

Building a ListView which scrolls neatly by item
Recently I wanted to horizontally scrolling ListView to display a number of panels. This is relatively easy to achieve, but there were two things that I did not like about it. As it turns out both of these issues are also very easy to fix. First up, calculating the panel dimensions can be done by…
Using Provider to Share State Between Widgets
Today I needed to share a timer between two widgets. A quick search revealed that the way to go was to use Provider. So, as usual I looked for a good example of how to go about it. I didn’t actually find one, so instead I took a look at the official documentation (https://pub.dev/packages/provider). Unfortunately,…
Updating CocoaPods to run Flutter Apps on iOS
Having successfully run a couple of Flutter Apps on Android devices and the iOS Simulator (from AndroidStudio), I was not expecting there to be much of a problem getting my App running on iOS. Unfortunately as soon as I tried to run my code from XCode I hit an error A quick search revealed a…
Styling PopupMenuItem with Flutter themes
In my previous post I looked at creating a reusable popup menu in flutter and applying a flexible theme from ThemeData. After a bit of testing I’ve uncovered two minor wrinkles. The first is that the icons in my PopupMenuItem don’t take their style from iconTheme as I had anticipated. Instead, for some unknown reason…
Reusable overflow menu in Flutter
One of the problems of learning new languages is that the majority of example code shows only the simplest use cases. With Flutter particularly I have found that the samples in the documentation and answers available on Stack Overflow are built to solve specific single widget needs rather than being coded for reusability. When you…
Styling Flutter (Part 2)
As part of my flutter journey I have been updating an app I wrote a few years ago, and applying some dynamic themes to it. In part one (Styling Flutter – Nightmare in Themesville) we looked at how to use the ThemeData object to apply a dynamic dark theme to light theme switch. In this…
