Data binding with polymer.dart

In the first recipe, we will go through an example that shows the complete mechanics of working with a Polymer component and data binding, and at the same time emphasizes some important best practices to work with polymer.dart. You can find the code in the project bank_terminal. The app creates an object of class BankAccount (which can be found in the lib folder) and populates it with the data that is shown. You can also provide a transaction amount and the balance of the account is updated. This is depicted in the following screenshot:

How to do it...

Perform the following steps to bind data with polymer.dart:

1. First, install the polymer dependency in your project by adding polymer: ">=0.11.0 <0.12.0" to the pubspec.yaml file. Save the file in the editor and run pub get from the command line. This has to be accompanied by an import line; in web\bank_app.dart, we use import'package:polymer/polymer.dart'; but also in web\bank_app.html...
