9. A method of controlling a flow of fluid within a wellbore, comprising:
conveying a frac plug system in the wellbore, the frac plug system including a frac plug and a plug member, the frac plug including a slip and a setting cone, the plug member having seal at a first end;
coupling the plug seal to a setting rod via a frangible connection while the frac plug is conveyed into the wellbore;
constraining an axial movement of the slip via the plug member and the setting rod as the setting cone moves against the slip to set the frac plug in the wellbore;
releasing the plug member from the setting rod after the frac plug is set in the wellbore;
maintaining the plug member within the frac plug once the plug member is released while allowing the plug member to move within the frac plug to control a flow of fluid through the frac plug; and
controlling the flow of fluid in a first direction via the plug seal.
