The flash reads like any other memory, review structures, and pointers to structures, to access the block of flash you plan on using. Try to keep all of your data within a structure, it will be much easier to manage, and allow you to journal the data across an erased block before you need to erase again.

Review Cube/HAL examples for writing flash on the L4 parts. Flash must be erased before it can be (re)written.
