#
Getting started with NDK
#
Install
Ndk has a core package ndk and optional packages like rust_verifier and amber.
flutter pub add ndk
#
Import
import 'package:ndk/ndk.dart';
#
Usage
We strongly recommend using RustEventVerifier() for client applications. It uses a separate thread for signature verification and is therefore more performant.
How to install below.
import 'package:ndk/ndk.dart';
import 'package:ndk_rust_verifier/ndk_rust_verifier.dart';
// init
final ndk = Ndk(
NdkConfig(
eventVerifier: RustEventVerifier(),
cache: MemCacheManager(),
),
);
// usecase - query
final response = ndk.requests.query(
filters: [
Filter(
authors: ['hexPubkey']
kinds: [Nip01Event.TEXT_NODE_KIND],
limit: 10,
),
],
);
// result
await for (final event in response.stream) {
print(event);
}

Prerequisites ndk_rust_verifier
- android SDK (also for desktop builds)
- flutter SDK
- rust ( + toolchain for target)
Rust toolchain android:
rustup target add \
aarch64-linux-android \
armv7-linux-androideabi \
x86_64-linux-android \
i686-linux-androidRust toolchain ios:
# 64 bit targets (real device & simulator):
rustup target add aarch64-apple-ios x86_64-apple-ios
# New simulator target for Xcode 12 and later
rustup target add aarch64-apple-ios-sim
# 32 bit targets (you probably don't need these):
rustup target add armv7-apple-ios i386-apple-ios
#
Install
flutter pub add ndk_rust_verifier
flutter pub add ndk_amber
