importantBuiltinFunctions

Dart provides a variety of built-in functions that are important for various programming tasks. Here are some other important built-in functions in Dart:

1. String Functions:

   • toUpperCase() and toLowerCase(): Convert a string to uppercase or lowercase, respectively.

   • trim(), trimLeft(), and trimRight(): Remove whitespace from the beginning or end of a string.

   • contains(): Check if a string contains a substring.

   • replaceAll(): Replace all occurrences of a substring with another substring.

   • split(): Split a string into a list of substrings based on a delimiter.

2. List Functions:

   • add(): Add an element to the end of a list.

   • addAll(): Add all elements from another list to the current list.

   • remove(): Remove the first occurrence of a specific element from a list.

   • removeAt(): Remove an element at a specific index in a list.

   • indexOf(): Find the index of the first occurrence of a specific element in a list.

   • sort(): Sort the elements of a list.

   • forEach(): Iterate over the elements of a list.

3. Map Functions:

   • putIfAbsent(): Add a key-value pair to a map if the key doesn't exist.

   • remove(): Remove a key-value pair from a map.

   • containsKey() and containsValue(): Check if a map contains a specific key or value.

   • keys and values: Get the keys and values of a map as iterable collections.

4. Iterable Functions:

   • map(): Transform each element of an iterable into another value and return a new iterable.

   • where(): Filter elements in an iterable based on a condition and return a new iterable.

   • reduce(): Combine elements of an iterable into a single value using a specified function.

5. Type Conversion Functions:

   • int.parse(), double.parse(): Parse strings to convert them to integers or doubles.

   • toString(): Convert a value to a string.

   • isNotEmpty: Check if a string or collection is not empty.

6. File and I/O Functions:

   • File(): Create and manipulate files in Dart.

   • Directory(): Create and manipulate directories in Dart.

   • stdin.readLineSync(): Read input from the console.

7. Async and Future Functions:

   • Future: Represents a potentially long-running operation that may complete with a value or an error.

   • async and await: Used to work with asynchronous operations.

   • Future.then() and Future.catchError(): Handle the results or errors of asynchronous operations.

8. DateTime Functions:

   • DateTime.now(): Get the current date and time.

   • DateTime.parse(): Parse a string to create a DateTime object.

   • DateTime.add() and DateTime.subtract(): Add or subtract time intervals from DateTime objects.

9. Assertion Functions:

   • assert(): Used for debugging and testing to check if a condition is true; if false, it throws an AssertionError.

These are just some of the important built-in functions and methods available in Dart. Depending on your programming needs, you may use these functions to perform a wide range of tasks, from string manipulation and data transformation to working with collections and asynchronous operations.
