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 .

Once we have node installed, we only need one command to install Truffle: npm install -g truffle

We will also be using 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.

• 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.

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:

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 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.

• Running the test as: truffle test
• If all the test pass, you’ll see the console output similar to this:

📁 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.
