`logging.FileHandler` not adding new lines to log file

Just tried the updated logging module to replace the StreamHandler and FileHandler adapted from CPython that I was previously using. Thank you @iabdalkader for this update.

StreamHandler works as expected, however I noticed that I wasn't getting any new lines in my log file.
I looked at the previous code and saw that there's a flush after the write in StreamHandler.emit.
Using this subclass for FileHandler, it works like before:

class MyStreamHandler(StreamHandler):

    def flush(self):
        if self.stream and hasattr(self.stream, "flush"):
            self.stream.flush()

    def emit(self, record):
        super().emit(record)
        self.flush()

Is there a reason for not doing a flush in emit, maybe something specific to MicroPython that I'm not aware of?

• MicroPython and board: MicroPython v1.19.1-915-g2bcd88d55 on 2023-03-02; Raspberry Pi Pico W with RP2040
• logging version: 0.5 installed with mip

Comienza reproduciendo el problema con el módulo de logging actualizado en la configuración de MicroPython Raspberry Pi Pico W indicada y, después, compara FileHandler con StreamHandler.emit y con la implementación adaptada anterior. Se considera terminado cuando la salida de logs de FileHandler esté disponible como se espera sin la subclase personalizada de flush; comprueba las pruebas de logging existentes si las hay.
