Any contract that calls IDragonswapV2PoolActions#flash must implement this interface

Functions

dragonswapV2FlashCallback

  function dragonswapV2FlashCallback(
    uint256 fee0,
    uint256 fee1,

  ) external

Called to msg.sender after transferring to the recipient from IDragonswapV2Pool#flash.

In the implementation you must repay the pool the tokens sent by flash plus the computed fee amounts. The caller of this method must be checked to be a DragonswapV2Pool deployed by the canonical DragonswapV2Factory.

Parameters:

The fee amount in token0 due to the pool by the end of the flash

fee1

uint256
