Type Inference and Annotation
Explore the concepts of type inference and annotation in Dart to understand how variables can be declared without explicit types. Learn to check variable types at runtime and use annotations to avoid type errors, enabling more flexible and robust code in your Dart programs.
We'll cover the following...
Overview
Dart is strongly typed. Strongly typed languages take extra precautions and have rules and restrictions to ensure that a variable’s value always matches the variable’s static type.
Statically typed programming languages are those in which variables need to be defined before they are used.
Although types are mandatory in Dart, type annotations are optional because of type inference.
Let’s first understand what type of inference is.
What is type inference?
As the name implies, type inference is a programming language’s ability to infer types when not specified by ...
