backToForm method
void
backToForm()
Return to the form from the review/result/queued screens (the Back / Send another / Edit actions). A no-op mid-flight (a transient state) so a stray tap can't abandon an in-flight sign.
Implementation
void backToForm() {
if (state is SendPreparing ||
state is SendSubmitting ||
state is SendQueuing) {
return;
}
_set(const SendForm());
}
