Pretty sure you have to say that computer_action=0 if you want to end or change the 0 with another number like 3 to continue with your questions

if computer_action == 1:

It is possibly because there are errors (exceptions) when the rendering is running. Have you checked whether there is an exception? For example, if you are using error-reporting tools like Sentry, go to its webpage to see. If you do not have one, try to see logs. Or, setup error handling (e.g. simply print it) following the official guide: https://flutter.dev/docs/testing/errors.

If you cannot find out any clues, try to setup error handling and put all logs here and I can try to see it.

EDIT

With more info, I can explain what happens.

The problem is that you are considering your list as a bidimensional one, but it isn't. You are using 4 different lists. So you don't need j in general. You should use something like this.

You can fix this issue by modifying your createdAt and updatedAt properties like below and also, modify your getter and setters.

Use Group-Object to group the rows by Id, then pick the one with the newest date from each group with Sort-Object -Descending |Select -First:

Add this line to the script:

You just declare the name and type of the tuple's properties like you would any other:

Rules for memory allocation.

• Do not allocate so much RAM that swapping will occur. Swapping is terrible for MySQL/MariaDB performance.
• Do adjust innodb_buffer_pool_size such that most of RAM is in use during normal time and even for spikes in activity. (I often say "set it to 70% of available RAM", but you are asking for more details.)
• Do not bother changing other settings; they add to the complexity of "getting it right".

There are 3 situations (based on innodb_buffer_pool_size and dataset size):

• Tiny dataset -- buffer_pool is bigger than necessary --> wasting some of RAM, but so what; it is not useful for anything else. And it give you some room for growth.
• Medium-sized dataset -- Most activity is done in RAM; the system will run nicely.
• Big dataset -- The system may be I/O-bound. Adding RAM is a costly and brute force solution. However, some software techniques (eg, better indexes) may help, such as this for WordPress and WooCommerce.
