PlatformTextInputInterceptor

suspend fun interceptStartInputMethod(
    request: PlatformTextInputMethodRequest,
    nextHandler: PlatformTextInputSession
): Nothing

Called when a function passed to establishTextInputSession calls startInputMethod. The PlatformTextInputMethodRequest from the caller is passed to this function as request, and this function can either respond to the request directly (e.g. recording it for a test), or wrap the request and pass it to nextHandler. This function must call into nextHandler if it intends for the system to respond to the request. Not calling into nextHandler has the effect of blocking the request.

This method has the same ordering guarantees as startInputMethod. That is, for a given text input modifier, if startInputMethod is called multiple times, only one interceptStartInputMethod call will be made at a time, and any previous call will be allowed to finish running any finally blocks before the new session starts.
