How should you properly design a platform channel's own specific API to genuinely minimize the total number of separate individual round trips genuinely required between Dart and native code, meaningfully improving overall performance for a genuinely frequently used specific native capability?

Since every single individual platform channel call genuinely involves some measurable amount of inherent serialization and cross platform boundary communication overhead, a genuinely well designed platform channel API should be properly structured to batch together several genuinely related individual operations into just one single combined method call wherever reasonably possible, rather than requiring several genuinely separate individual round trips for what is conceptually really just one single logical overall operation, which becomes particularly important for a genuinely frequently called native capability, such as one invoked repeatedly many times per second, where that accumulated inherent per call overhead could otherwise genuinely and meaningfully begin to noticeably affect your app's own overall performance.

// Less efficient: multiple separate round trips
// await platform.invokeMethod('setX', x);
// await platform.invokeMethod('setY', y);

// More efficient: one single combined round trip
await platform.invokeMethod('setPosition', {'x': x, 'y': y});
