Overview
web3_webview is a Flutter package that establishes secure, bidirectional communication between a DApp loaded in a WebView and the host Flutter application. It acts as a bridge, allowing seamless data exchange for blockchain interactions such as wallet connections, transaction signing, and event handling. Designed for Web3 applications, it ensures safe integration with web-based smart contracts and decentralized services. The package supports multiple platforms including Android, iOS, macOS, and Windows, making it ideal for cross-platform DApp development. Its lightweight design and straightforward API simplify embedding web-based blockchain functionality into native Flutter apps.
