Before learning Flutter app development, it is helpful to have a good understanding of the Dart programming language. Some of the key concepts of Dart that you should be familiar with include:
Data types: Dart has a number of built-in data types, including numbers, strings, booleans, and collections (e.g. lists and maps). You should be familiar with the syntax for declaring and using variables of these types, as well as the operations and methods that are available for each type.
Functions: Dart allows you to define your own functions, which are named blocks of code that can be called to perform a specific task. You should be familiar with the syntax for defining and calling functions, as well as the concept of parameters and return values.
Classes and objects: Dart is an object-oriented programming language, which means that it allows you to define classes that can be used to create objects. You should be familiar with the syntax for defining classes, as well as the concept of fields, methods, and constructors.
Async programming: Dart supports asynchronous programming, which means that you can write code that can perform long-running tasks without blocking the execution of other code. You should be familiar with the async and await keywords, as well as the Future and Stream classes, which are used to manage asynchronous operations in Dart.
Package management: Flutter uses a package manager called pub to manage the dependencies of your app. You should be familiar with the basics of using pub, including how to add, update, and remove packages from your app.
Overall, these are some of the key concepts of the Dart programming language that you should be familiar with before learning Flutter app development. By understanding these concepts, you will be well-equipped to start building your own Flutter apps.
