What methods can be used to eliminate the problem of unexpected application shutdown during its operation?

Unexpected app closure during operation (crash) can be caused by various reasons. To fix this issue, you can use the following approaches:

• Logging and debugging: Use debugging tools (e.g., Flutter DevTools) and add logging to understand where exactly the error occurs.
• Exception handling: Wrap critical sections of code in try-catch blocks to intercept and handle errors properly.
• Using FlutterError.onError: Allows intercepting unhandled errors in Flutter and logging them.
• Memory status check: Sometimes the app crashes due to insufficient memory; optimize resource usage.
• Testing on different devices and OS versions: Sometimes the problem is related to a specific platform or version.
• Using crash report collection tools: For example, Firebase Crashlytics helps collect crash information in production.

Example of error handling in Flutter:

FlutterError.onError = (FlutterErrorDetails details) {
  // Log the error
  print('Flutter error: ${details.exceptionAsString()}');
  // You can also send data to a server or show it to the user
};

try {
  // Code that might throw an exception
} catch (e, stackTrace) {
  print('Caught error: $e');
}
