Explain what is meant by the term PDD in the context of software development.

PDD (Programming Driven Development) is an approach to software development where the main focus is on writing code and implementing functionality, rather than detailed preliminary design.

In the context of development, PDD implies:

• Rapid iterative development with frequent changes.
• Emphasis on practical problem solving through programming.
• Minimal formal documents and specifications.

This approach is often contrasted with more formal methodologies such as TDD (Test Driven Development), where tests are written before code, or Waterfall, where detailed documentation is created first.

In Flutter development, PDD can mean quick prototyping of UI and logic, with subsequent refinement as needed.
