Flutter Fundamentals

Widgets and UI Toolkit

Flutter is an open-source UI toolkit that allows developers to create natively compiled applications for mobile, desktop, and web platforms. The heart of Flutter lies in its widgets. Examples of widgets include:

  • Text input fields
  • Buttons
  • Icons

Widgets define the visual appearance of an app and handle user interactions. Flutter uses a declarative approach, in which the user interface is described by a tree of these widgets.

State Management and Stateful Widgets

Managing the state of an app is essential in Flutter due to its reactive nature. This can be achieved through various patterns, such as:

  • setState (In-built method)
  • Provider package
  • BLoC Pattern

Stateful Widgets are a specific type of widget that can hold mutable state, allowing the widget to redraw itself when required. For instance, a checkbox is a stateful widget because the UI changes after checking or unchecking it.

Package and Plugin Ecosystem

Flutter has a rich package and plugin ecosystem. These packages offer pre-built functionality, making it easy for developers to extend the capabilities of an app. Examples of popular packages:

  • http: For making HTTP requests
  • shared_preferences: For storing key-value data on the device

Flutter packages can be found on pub.dev, the official package repository for the Dart programming language used in Flutter.

Navigation and Routing

In a Flutter app, you need to manage the navigation between different screens or pages. This is achieved by using Flutter’s built-in navigation and routing system. Below are the key components:

  • Navigator: The central object responsible for managing navigation stack
  • Route: A definition of a screen or page
  • MaterialPageRoute: A material design route for MaterialApp widgets

Here’s a comparison table of various Flutter features and components:

Feature/Component Description Example
Widgets Building blocks of the UI Text, RaisedButton, SizedBox
State Management Manage and update app state setState, Provider
Packages Add extra functionality to your app http, shared_preferences
Navigation Handle movement between app screens/pages Navigator, MaterialPageRoute

Developing Apps with Flutter

Creating a Basic App

Flutter is a popular framework for mobile development that helps you build high-quality mobile apps quickly. To create a basic Flutter app, follow these simple steps:

  1. Install Flutter SDK and Dart on your computer.

Letter 1 – Flutter Fly


Subject: Flying Appalachian Ugly Bug
Location: Appalachian part of New York State
August 26, 2012 4:14 pm
I was told about your website by a California lady that takes beautiful pictures of beautiful bugs. I grabbed my camera to see what kind of bug pictures I could take.
This picture was taken at approximately 42.074009N and 76.847949W at about 0730 on 25 August 2012. It is a wooded area just about 15 yards north of the Chemung River.
It is a rather ugly bug and it was eating(?) breakfast(?) on a leaf.
Can you identify either the breakfast or the bug?
Signature: whytepaper

Flutter Fly

Dear whytepaper,
We quickly identified your Flutter Fly in the genus
Toxonevra thanks to bugGuide.  We thought it resembled the Picture Winged Flies, and it is classified in the same superfamily Tephritoidea.  According to the Flutter Fly family page on BugGuide:  “larvae phytophagous or predaceous on longhorn & bark beetle larvae (Cerambycidae, Curculionidae: Scolytinae)” and the adults are found “on flowers and low-hanging branches in shady habitats, larvae under bark, and in flower buds and stems.”  This represents a new family for our website.

Mr. Marlos,
Thank you so much for identifying the flutter fly.  I am just beginning and will try and study your sight so I won’t bother your staff with boring pictures.
Anna Carreon told me that she has already sent you a note that she is the California Lady whose pictures I am envious of.
Thank you again for the rapid response to the flutter fly identification.
