What is the difference between 'final' and 'const' in Dart?
- 'const' variables can be changed at runtime
- 'const' variables must be initialized at compile-time
- 'final' variables are implicitly constant
- 'final' variables must be initialized at runtime
The main difference between 'final' and 'const' in Dart is that 'final' variables must be initialized at runtime, whereas 'const' variables must be initialized at compile-time. 'final' is used for variables that can be set only once, but their value can be determined during runtime. On the other hand, 'const' is used for values that are known at compile-time and remain constant throughout the program's execution. Understanding this distinction is crucial for effective Dart programming.
