Type Inference and Annotation

Dart is a strongly and statically typed language, allowing the compiler to check variable types at compile-time to prevent errors. Type inference enables the compiler to automatically determine types using the `var` keyword, while explicit type annotations can be used for more precise control. Dart enforces null safety, inferring non-nullable types unless specified otherwise. The `dynamic` keyword disables static type checking, allowing variables to hold multiple types, but should be used cautiously to maintain safety. Overall, Dart promotes a structured approach to type management through explicit types, inference, and dynamic typing.

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.
