The try...catch block in Dart/Flutter can prevent the application from crashing by catching and handling exceptions that can occur during runtime. When an exception is thrown, the code execution stops and the program crashes or terminates. The try...catch block allows developers to handle these exceptions gracefully by providing a mechanism to catch and handle exceptions, thereby preventing the application from crashing.

By wrapping the code that is likely to throw an exception in a try block, the developer can catch the exception in the catch block and handle it appropriately. For example, if the code is performing file I/O and the file is not found, the catch block can display an error message to the user instead of crashing the application.

Overall, using try...catch blocks in Dart/Flutter can make the application more stable and robust by handling exceptions gracefully and preventing crashes.
