SwitchFSM.string(RunTime): 92.31338451577098 us. Both AOT and dart2js are 'good at' switches on enum values. When compiled with --enable-experiment=records,patterns: AOT: SwitchFSM.enum(RunTime): 141.75470079359405 us. SwitchFSM.int(RunTime): 145.25322604030737 us. SwitchFSM.class(RunTime): 138.45460840662005 us. SwitchFSM.string(RunTime): 797.226 us. dart2js+V8: SwitchFSM.enum(RunTime): 98.93787283573403 us. SwitchFSM.int(RunTime): 29.459852700736498 us. SwitchFSM.class(RunTime): 98.62184338405162 us. SwitchFSM.string(RunTime): 92.035889371936 us. There is work to be done to recover the performance.
