RCTRenderingPerf does not expose ReactPerf.printExclusive()

[beeglebug]

Description

When calling RCTRenderingPerf.stop, we automatically get the output from ReactPerf.printInclusive() and ReactPerf.printWasted(), but have no way of getting ReactPerf.printExclusive(), as it is not exposed by the module.

Reproduction Steps and Sample Code

The following code will trigger the output from printInclusive and printWasted:

import PerfMonitor from 'react-native/Libraries/Performance/RCTRenderingPerf'

PerfMonitor.toggle()
PerfMonitor.start()
setTimeout(() => {
    PerfMonitor.stop()
}, 1000)

Solution

Expose the output functions to be called directly instead of automatically calling some inside stop.

import PerfMonitor from 'react-native/Libraries/Performance/RCTRenderingPerf'

PerfMonitor.toggle()
PerfMonitor.start()
setTimeout(() => {
    PerfMonitor.stop()
    PerfMonitor.printExclusive()
    PerfMonitor.printInclusive()
    PerfMonitor.printWasted()
}, 1000)

I am happy to do a merge request for this.
