isDefault property

bool? isDefault
getter/setter pair

Whether this address is selected as the default "From:" address in situations such as composing a new message or sending a vacation auto-reply.

Every Gmail account has exactly one default send-as address, so the only legal value that clients may write to this field is true. Changing this from false to true for an address will result in this field becoming false for the other previous default address.

Implementation

core.bool? isDefault;
