In programming language theory, flow-sensitive typing (also called flow typing or occurrence typing) is a type system where the type of an expression depends on its position in the control flow. In statically typed languages, a type of an expression is determined by the types of the sub-expressions that compose it. However, in flow-sensitive typing, an expression's type may be updated to a more specific type if it follows an operation that validates its type. Validating operations can include type predicates, imperative updates, and control flow.

- En teoría de lenguaje de programación, tipado sensitivo al flujo es un sistema de tipos donde el tipo de una variable es determinado por el flujo de control. Clásicamente, en los lenguajes con tipado estático, una variable queda ligada a un tipo durante todo su tiempo de uso. En los sistemas de tipado sensible al flujo, el tipo de una variable puede cambiar dentro del cuerpo de un método, mientras atraviesa (o fluye a través de) las estructuras de control. El tipo se determina usando inferencia de tipos y la información de tipos fluye usando Tipo de dato algebraico. (es)

| - The citation later is for the quote, flow sensitive typing doesn't seem to improve null-safety, a null-safe type system will. Possible confusion as these languages have nullable/non-nullable types, as checking null-safety through flow-sensitive typing generally equates to a null check without it (en)
