What types of information are permissible to transmit through isolated environments in the system?

In isolated environments (for example, isolated isolates or isolates in Flutter), it is recommended to pass only simple and safe data that does not break isolation and does not create dependencies.

Permissible types of information:

• Primitive types (numbers, strings, boolean values)
• Simple data structures (lists, maps) consisting of primitives
• Objects that can be serialized and safely passed between isolates

Cannot pass:

• References to objects related to UI or state
• Input/output streams, sockets, descriptors
• Any objects that do not support serialization or require shared state

This ensures the safety and independence of isolated environments.
