Intro
Why Polkadart?
Discover why Polkadart is the ideal choice for building blockchain applications with Dart and Flutter
The Power of Dart Meets Blockchain
Polkadart brings together the best of both worlds: Dart's modern development experience and Polkadot's innovative blockchain technology. Here's why developers choose Polkadart for their decentralized applications.
🎯 Key Advantages
Generated types from chain metadata ensure compile-time safety and eliminate runtime errors
Single codebase runs on iOS, Android, Web, Desktop, and Server environments
Auto-completion, inline documentation, and familiar Dart syntax speed up development
Native compilation and efficient SCALE codec implementation for blazing-fast execution
💙 Why Dart for Blockchain?
Familiar and Approachable
Dart's clean syntax makes blockchain development accessible:
// Simple and readable transaction code
final transfer = await polkadot.tx.balances
.transfer(
dest: recipientAddress,
value: BigInt.from(1000000000000), // 1 DOT
)
.signAndSend(keyring);
Built for Production
- Sound null safety prevents common bugs
- Strong typing catches errors early
- Async/await simplifies complex blockchain operations
- Hot reload speeds up development (Flutter)
