Is it a question of limits? What's the limit? Thanks Simo Removed default null values since there is no common standard that could be found. Removed default boolean values of yes, y, no, n since it's not a standard boolean. true, false, 1, 0 still work. Changed default delimiter to , instead of ListSeparator.

hope it's clear. can you still help anybody Line 47, field missing > MissingFieldFound w/ headernames null Gets or sets the function that is called when a missing field is found.The default function will throw a CsvHelper.MissingFieldException.You can supply your own function to do other things like logging the issue instead of throwing an exception.
This is a way of running programs and making sure they produce NO output and will never be seen on the command line or in a log file. Migrating a Flutter app to null safety can be surprisingly painless. Leaf Petersen demonstrates how to use pub to find out if you're ready to migrate, and ho If you want to have it output something else, you could create a custom type converter that you use for that field. If it's null, conver to "null", otherwise get the default type converter for that type and return the result of that instead. Having a config for a custom null value when writing would be a nice feature.
Fourth, once null references are used as valid states for parameters as well as return values, defensive programming (for states caused by design) requires more null reference checking to be done in various places…just in case.

Как я понял, нужно создать обработчик события, который будет приравнивать BadDataFound к нулю, но как это сделать Думаю, что можно через try-catch, но не изучил этот пункт :c.
Most of the changes that your code needs to be null safe are easily predictable.
