Cross-Platform UIs with Flutter

Overview of this book

Flutter is a UI toolkit for building beautiful, natively compiled applications for mobile, web, desktop, and embedded devices from a single code base. With Flutter, you can write your code once and run it anywhere using a single code base to target multiple platforms. This book is a comprehensive, project-based guide for new and emerging Flutter developers that will help empower you to build bulletproof applications. Once you start reading book, you’ll quickly realize what sets Flutter apart from its competition and establish some of the fundamentals of the toolkit. As you work on various project applications, you’ll understand just how easy Flutter is to use for building stunning UIs. This book covers navigation strategies, state management, advanced animation handling, and the two main UI design styles: Material and Cupertino. It’ll help you extend your knowledge with good code practices, UI testing strategies, and CI setup to constantly keep your repository’s quality at the highest level possible. By the end of this book, you'll feel confident in your ability to transfer the lessons from the example projects and build your own Flutter applications for any platform you wish.

Setting up the project

To really get started, create a new Flutter project with your favorite integrated development environment (IDE) to get the skeleton of a minimal, working Flutter app. Next, open the pubspec.yaml file and make sure to have these two dev dependencies installed:

dev_dependencies:
  # https://pub.dev/packages/dart_code_metrics
  dart_code_metrics: ^4.9.1
  # https://pub.dev/packages/flutter_lints
  flutter_lints: ^1.0.4

We’re now going to dedicate some time to work on the analysis_options.yaml file. Very simply, this file contains a series of static analysis rules to help you with writing readable, high-quality code. By default, a new Flutter project already creates this file for you with a minimal setup (we have removed comments for simplicity), as illustrated in the following code snippet:

include: package:flutter_lints/flutter.yaml
linter:
  rules:
    avoid_print: false
