	amount1Desired string,
	amount0Min string,
	amount1Min string,
	deadline int64,
	mintTo string
) (uint64, string, string, string)

token1	string	The path of the token1 of the desired pool.
fee	uint32	The fee tier of the pool.
tickLower	int32	The lower tick of the price range of the position.
tickUpper	int32	The upper tick of the price range of the position.
amount0Desired	string	The maximum amount of token0 to add.
amount1Desired	string	The maximum amount of token1 to add.
amount0Min	string	The minimum amount of token0 to add.
amount1Min	string	The minimum amount of token1 to add.

	liquidityRatio uint64,
	_amount0Min string,
	_amount1Min string,
