Combining Flutter with Protobuf to build a powerful mobile app
summary
Demonstrates using Protobuf with Flutter and native code via the Protobuf compiler and method channels, with a Rust test server sending 10k–1M records; claims modest CPU/time gains but large bandwidth and storage savings. Shows generated Dart/Java code parsing bytes into objects, local-file tests where parsing 100,000 items takes 76 ms with Protobuf versus 195 ms for JSON, and file sizes roughly 4 MB vs 6 MB; method-channel transfer of 100,000 items measures 37 ms versus 195 ms using Pigeon.
