[Contract Git Source](https://github.com/dopex-io/dopex-v2-clamm/blob/c47ed162e778d188e077b6b1874a8b5873e15c1d/src/DopexV2PositionManager.sol)

Mint a new position using the specified handler.

```solidity
function mintPosition(IHandler _handler, bytes calldata _mintPositionData)
    external
    onlyWhitelistedHandlers(_handler)
    nonReentrant
    returns (uint256 sharesMinted);
```

**Parameters**

| Name                | Type       | Description                             |
| ------------------- | ---------- | --------------------------------------- |
| `_handler`          | `IHandler` | The address of the handler to use.      |
| `_mintPositionData` | `bytes`    | The data required to mint the position. |

**Returns**

| Name           | Type      | Description                  |
| -------------- | --------- | ---------------------------- |
| `sharesMinted` | `uint256` | The number of shares minted. |

The \`\_mintPositionData\` parameter has to be constructed the following way:

```solidity
struct MintPositionParams {
    IUniswapV3Pool pool;
    address hook;
    int24 tickLower;
    int24 tickUpper;
    uint128 liquidity;
}

bytes memory _mintPositionParams = abi.encode(
    _params.pool,
    _params.hook,
    _params.tickLower,
    _params.tickUpper,
    _params.liquidity
);

// To decode:
MintPositionParams memory decodedParams = abi.decode(encodedData, (MintPositionParams));
```

### **MintPositionParams Struct**

| Field Name | Type           | Description                      |
| ---------- | -------------- | -------------------------------- |
| pool       | IUniswapV3Pool | The Uniswap V3 pool contract     |
| hook       | address        | The address of the hook contract |
| tickLower  | int24          | The lower tick of the position   |
| tickUpper  | int24          | The upper tick of the position   |
| liquidity  | uint128        | The amount of liquidity to mint  |
