Protocol-buffers – maximum serial Protobuf message size
Is there a way to get the maximum size of a protobuf message after serialization?
I am referring to messages that do not contain “duplicate” elements.
Please note that I am not referrin
PROTOBUF text format analysis map
This answer clearly shows some examples of raw text parsing, but no examples of maps.
If a prototype has:
map aToB I guess it is like this:

How to use Dart-Protobuf

Protocol-buffers – Protobuf3: How to describe the mapping of repeating strings?
Official documentation about map type says:
map map_field = N ;
…where the key_type can be any integral or string type (so, any
scalar type except for floating point types and bytes).
