RequestDartPerformanceMode()

int flutter::PlatformConfigurationNativeApi::RequestDartPerformanceMode ( int  mode )

static

Requests the Dart VM to adjusts the GC heuristics based on the requested performance_mode. Returns the old performance mode.

Requesting a performance mode doesn't guarantee any performance characteristics. This is best effort, and should be used after careful consideration of the various GC trade-offs.

Parameters

[in]

performance_mode

The requested performance mode. Please refer to documentation of Dart_PerformanceMode for more details about what each performance mode does.
