The discussion focuses on the shortcomings of Dart and Flutter's pseudo-random number generators (PRNGs) and the implications of using insecure random number generation in applications. Users highlight that while Dart offers a secure random generator option, many developers opt for the faster non-secure variant for performance reasons. Concerns are raised about the design choices in modern programming languages regarding PRNGs, emphasizing that defaults should ideally be cryptographically secure to avoid inadvertent security vulnerabilities. Furthermore, comments illustrate the broad problem across various programming languages, as multiple popular languages also employ non-secure random generators by default, leading to critical issues when used in sensitive applications. The conversation critiques the inherent nature of PRNGs being insecure by design, necessitating developers to be mindful of the specific use cases of these generators and choose appropriate ones for their needs.
