generateProof method
Generates a Merkle proof for a specific leaf
Implementation
MerkleProof<T> generateProof(int leafIndex) {
if (root == null || leafIndex < 0 || leafIndex >= leafCount) {
throw ArgumentError('Invalid leaf index: $leafIndex');
}
final proof = <String>[];
final directions = <bool>[];
_generateProofRecursive(root!, leafIndex, 0, proof, directions);
return MerkleProof<T>(
hashes: proof,
directions: directions,
leafIndex: leafIndex,
totalLeaves: leafCount,
);
}
