## Setting up the development environment
Truffle is the most popular development framework for Ethereum with a mission to make your life a whole lot easier. But before we install truffle make sure to install [**node**](https://nodejs.org/en/) .
Once we have node installed, we only need one command to install Truffle:
**`npm install -g truffle`**
We will also be using [**Ganache**](http://truffleframework.com/ganache), a personal blockchain for Ethereum development you can use to deploy smart contracts, develop applications, and run tests. You can download Ganache by navigating to http://truffleframework.com/ganache and clicking the “Download” button.
## Directory Structure
- **contracts/** : Contains solidity contract file.
- **migrations/** : Contains migration script files (Truffle uses a migration system to handle contract deployment).
- **test/** : Contains test script files.
- **truffle-config.js** : Contains truffle deployment configurations information.
## Compiling and Migrating Smart Contract
### Compilation
In the terminal, make sure you are in the root of the directory that contains the flutter and truffle project, Run the following command:
**`truffle compile`**
You should see output similar to the following:
### Migration
Before we can migrate our contract to the blockchain, we need to have a blockchain running.
We’re going to use **Ganache**, a personal blockchain for Ethereum development you can use to deploy contracts,
develop applications, and run tests.
If you haven’t already, download [**Ganache**](http://truffleframework.com/ganache) and double-click the icon to launch the application. This will generate a blockchain running locally on port 7545.
- Migrating the contract to the blockchain, run: **`truffle migrate`**
You should see output similar to the following:
- Take a look into the Ganache, the first account originally had 100 ether, it is now lower, due to the transaction costs of migration.
## Testing the Smart Contract
- Running the test as: **`truffle test`**
- If all the test pass, you’ll see the console output similar to this:
## Contract Linking
```
📁 project(eg. helloworld,bidder,...)
📁 lib
🎯 contract_linking.dart
- Update _rpcUrl, _wsUrl, _privateKey as per your needs.
```
- You can get the RPC URL from the ganache :
- Get the Private Key from ganache:
- After Contract Linking, Just run the Flutter Project.
