* @dev Mint ERC20 rewards to the staker. Must override. @param _staker Address for which to calculated rewards. @param _rewards Amount of tokens to be given out as reward./ Mint or transfer reward-tokens here. e.g. OR Use a mintable ERC20, such as thirdweb's `TokenERC20.sol`TokenERC20(rewardToken).mintTo(_staker, _rewards); note: The staking contract should have minter role to mint tokens.
