![]() Inside your mason.yaml file, add the brick name and the GitHub repository link.Import 'package:flutter/material. You can also use bricks directly from GitHub repositories. We will be talking about how to reuse widgets and create custom reusable AppBars in this article. Congratulations, you have generated a Flutter widget using bricks and the Mason CLI. ![]() Then provide all the variables you have defined in the bricks.yaml file. 5.29K subscribers Subscribe 290 15K views 1 year ago Flutter Development This tutorial goes through how to create custom, reusable widgets in Flutter. To generate a file using our widget brick with the Mason CLI, run the mason make widget command. Now use the mason make command to generate files in the current working directory. First, run mason list to list all the available bricks. This is required to personalize our app for the app users while promoting code reusability. Now that we have successfully created and registered our brick, let’s start using it to generate files using the Mason CLI. In this post, we discuss how to reuse our all farmer screen widget. Your widget brick is now ready to generate stateless or stateful widgets on demand using the Mason CLI. Let’s run the mason get command to register all the bricks from the nearest mason.yaml file. I will also add an appbar inside the scaffold and use the filename variable as an appbar title. (If you’re not familiar with the Mustache syntax and want some detailed information, take a look here.) To define a variable, you can use the syntax to convert the filename variable into Pascal case. A primer on mustache syntaxīricks use the Mustache syntax to add variables and conditionals in your file. You can also create a brick for unit tests and generate multiple test files in one go using the power of the Mason CLI and bricks. If you are familiar with Flutter unit testing and widget testing, you know that the basic structure of all the tests is the same. You can also use variables and conditionals in these templates to give each page a different name and structure.Īnother common use of bricks is generating test files. But using bricks, you can write a template Flutter page and generate new pages on the fly. So in the main.dart file i am making a component which is basically a bunch of widgets wrapped together. Normally, if your Flutter project needs multiple pages, you have to write the same repetitive code multiple times. Need help in making a reusable widget in flutter. A page in your Flutter app may be stateful or stateless depending on its reactivity to the state change, and in general, each page contains a scaffold and an appbar. Let’s learn about bricks and Mason with a simple example. Therefore, you should have Dart installed on your computer before you install the Mason CLI. Mason is written in the Dart programming language. You can now play with it live in your browser. What you’ll learn in this tutorialĪt the end of this tutorial, you’ll learn how to:Įxcited? Make sure to follow the tutorial to the end to get a complete picture of bricks and Mason.īelow, you can find the complete Mason sample project. Mason can be very useful in larger projects, as it provides a definite guideline to developers and helps maintain consistency in code. Once brick templates are defined, developers use the Mason CLI to create, manage, and generate new files from these bricks. ![]() Generics with Collections: You can declare collection variables. We will also explore the differences and see how Hook widgets can be used over Stateful widgets to improve app performance. In this article, we will explore the different types of widgets (Stateless and Stateful) and also look into Hook widgets, an extension to Stateless widgets. A brick can be a file or a collection of nested files and directories. Generics help composes reusable classes, methods/functions for various information types. Everything in Flutter is made up of widgets. These reusable templates are called bricks. It is used to generate files and directories from predefined templates to enhance developer productivity. Mason is an open-source template generator created by Felix Angelov from Very Good Ventures. So Create a new file appbar.dart and I am gonna name by class IAppBar. Yes, it needs a size So let’s see in that case how can we create a reusable AppBar. Alternatively, you can use bricks made by others from GitHub or v. Creating a reusable AppBar is little different. or you can use them to build smaller, reusable components that can be. You can use Mason in your Flutter projects by first creating and registering the templates (aka bricks) and then utilizing them to create files and folders. In Flutter, widgets are the basic building blocks of the app's user interface. TL DR: Mason is a Dart package that allows you to create files and directories based on templates. This post is written by Hrishikesh Pathak Reusable widgets: functions or classes Marc Basics Beginner Dart 2.8.4 Flutter 1.17.3 Reusability Widget Every software project that has reached a certain level of complexity and size requires a certain structure in order to stay maintainable.
