+In Dart, **`.tryParse()`** is a static method available on several data types, such as `int` and `double`, for example. When called on a `string`, the `.tryParse()` method attempts to parse the string and returns a nullable value of the target data type if the parsing is successful. However, if parsing fails due to an invalid format in the string, the method returns `null`.
+
+## Syntax
+
+```pseudo
+dataType.tryParse(stringToParse)
+```
+- `stringToParse` - Represents the `string` to be converted into the desired data type.
+- `dataType` - Represents the data type to be converted to stringValue.
+
+## Example
+
+```dart
+void main() {
+  String input = '42';
+  int? parsedInt = int.tryParse(input);
+
+  if (parsedInt != null) {
+    print('Parsed integer: $parsedInt');
+  } else {
+    print('Failed to parse the string as an integer');
+  }
+}
+```
+The above code will return the following output: 
+
+```dart
+//Parsed integer: 42
+```
