Define a final category list and render a horizontal list view with a bold categories header. Set up a structured grid view to show products.

Create a two-column Flutter grid view to showcase products with images and names, and add a floating action button to navigate to product creation.

Fix the grid view item in Flutter by adjusting container size, context, and shrinkWrap, then navigate to the product detail page via a tap.

Design a Flutter create product page with a single scrollable column, text inputs for product name, price, and description, a category selector, and image picker.

Create a flutter dropdown list from a constant category list, map items to dropdown menu items, and update the selected value on change.

Build a product detail section with image fetch, category and icon rows, and interactive explore links using a scrollable column, color theming, and on-tap actions in a Flutter UI.

Create a seller card in Flutter by integrating a random avatar package, displaying the product title, description, price, and seller address with styled text and layout.

This lecture guides building a product detail page with price and a buy button, applying styling and alignment. It also covers blockchain features for NFT products, categories, and buy-sell workflows.

deploy a smart contract to a test net using remix and metamask, connect wallets across Polygon and other networks, obtain the contract address, and verify deployment on polio scan.

Connect a Flutter app to the blockchain using Infura endpoints over http and WebSocket, manage state with provider and change notifier, and fetch contract data for all accounts.

Set up a web3 client to connect to the blockchain network using https, socket io, and web socket libraries for real-time rpc calls and prepare for contract interaction.

Fetch the contract ABI and address from an API, convert the address to an Ethereum address in Dart, and prepare for deploying the contract in a Flutter app.

Connects to a deployed smart contract, retrieves the store name via a contract function, and displays it in the user interface while handling abi, address, and loading states.

Create a custom loader indicator in Flutter using a circular progress indicator inside a styled container, customizing size, color, and layout for reuse in app loading states.

Develop and test a function to fetch the store's product count, save the data privately, and prepare to loop through ids to fetch all products next.

Fetch all products data by integrating blockchain functions with a Flutter frontend, manage the NFT marketplace contract, build a product model, and populate a clean product list.

Build and store a blockchain product model by defining id, name, description, image, sold, price, and owner (Ethereum address) with a constructor and require checks to add products.

Showcases loading and retrieving products from a blockchain via a contract factory, then maps image, name, and price to the UI, converting big-integer prices for display.

Show a single product’s data by wiring the product model to the detail page, and display the title, image, category, description, owner, and price for blockchain purchases with connected wallets.

Build a wallet-connected profile page by integrating MetaMask and connecting wallet authentication. Install MetaMask on iPhone or Android, navigate to the account screen, and design with Material UI scaffolding.

Learn to install the wallet library, connect MetaMask on a testnet, and implement a connect wallet function using connectors to obtain a provider and session.

Connect to a wallet, fetch user account data, and display the address on a profile page using Flutter and WalletConnect, with session-driven navigation.

Create a get balance function to fetch a user’s ether balance, convert it from wei to ether units, and display it on the user card with proper account handling.

Create an add product function by validating inputs, connecting a web3 client, and retrieving wallet credentials; then call the contract's create product with name, description, image, price, and category.

Learn to create credentials from a wallet provider like MetaMask without exposing private keys, using an Ethereum provider, and override transaction sending to generate and use credentials.
