Shut water off at toilet and remove supply at tank connection. Get a bucket and test the flow of water by turning valve back on. If it is good then you know the problem is the fill valve. If you can't free any debris from the bottom of fill valve, replace it. Be sure before you reconnect supply to new valve after you flush out supply into bucket.
Should flow out of supply line be weak, the valve and supply should be changed. It is always good practice to replace the supply lines after working on fixtures. Faulty supply lines can cause considerable damage to your home. Always make sure connections are nice and snug (don't over tighten)
One more note: If your home still has galvanized piping, don't waste your money on new updated, high efficiency fixtures and appliances! They will ALL give you problems from the rust and corrosion that flows through your galvanized pipes. Today everything is designed for low flow, water saving and efficiency. That means they contain restrictive components which easily become congested from rusty galvanized piping! Call a professional to replace your entire water system from the source with copper. You can then enjoy the Tank-less water heaters, electronic faucets, pull out faucets and ultra low flow toilets with far fewer problems!
