Flutter

Flutter is Google's UI toolkit for creating beautiful and native applications for mobile, desktop and web from a single Dart codebase. In this book we cover in detail the Dart programming language (version 2.10, with null safety support) and the Flutter framework (version 1.20). While reading the chapters, you'll find a lot of good practices, tips and performance advices to build high quality products. The book is divided in 3 parts. PART 1: It's about the Dart programming language (classes, exceptions, inheritance, null safety, streams, SOLID principles...). PART 2. It's about the Flutter framework (localization, routing, state management with Bloc and Provider, testing, performances with DevTools, animations...). PART 3. It's a long collection of examples (using Firestore, monetizing apps, using gestures, networking, publishing packages at pub.dev, race recognition with ML kits, playing audio and video...). The official website of the book contains the complete source code of the examples and a "Quiz Game" to test your Dart and Flutter skills!

Ephemeral observations meet spiritual resilience in B. Miller’s poetry debut, Flutter By, composed over the past four years. Perspectives on life's torments and absurdities are starkly confronted, with some solace sprinkled in. This collection is for anyone at the intersection of the abyss and God’s caress.

Work in Flutter, a framework designed from the ground up for dual platform development, with support for native Java/Kotlin or Objective-C/Swift methods from Flutter apps. Write your next app in one language and build it for both Android and iOS. Deliver the native look, feel, and performance you and your users expect from an app written with each platform's own tools and languages. Deliver apps fast, doing half the work you were doing before and exploiting powerful new features to speed up development. Write once, run anywhere. Learn Flutter, Google's multi-platform mobile development framework. Instantly view the changes you make to an app with stateful hot reload and define a declarative UI in the same language as the app logic, without having to use separate XML UI files. You can also reuse existing platform-specific Android and iOS code and interact with it in an efficient and simple way. Use built-in UI elements - or build your own - to create a simple calculator app. Run native Java/Kotlin or Objective-C/Swift methods from your Flutter apps, and use a Flutter package to make HTTP requests to a Web API or to perform read and write operations on local storage. Apply visual effects to widgets, create transitions and animations, create a chat app using Firebase, and deploy everything on both platforms. Get native look and feel and performance in your Android and iOS apps, and the ability to build for both platforms from a single code base. What You Need: Flutter can be used for Android development on any Linux, Windows or macOS computer, but macOS is needed for iOS development.

Summary In 2017, consumers downloaded 178 billion apps, and analysts predict growth to 258 billion by 2022.

A “page-turner of a survival story.” –School Library Journal Big things are about to happen at Maple's house. Mama's going to have a baby, which means now there will be four Rittle sisters instead of just three. But when baby Lily is born too early and can't come home from the hospital, Maple knows it's up to her to save her sister. So she and Dawn, armed with a map and some leftover dinner, head off down a river and up a mountain to find the Wise Woman who can grant miracles. Now it's not only Lily's survival that they have to worry about, but also their own. The dangers that Maple and Dawn encounter on their journey makes them realize a thing or two about miracles-and about each other.
