Problem

👾 Description of the Issue

The central TransactionRecord class, located in src/hiero_sdk_python/transaction/transaction_record.py, is missing essential documentation on its aggregated fields and key helper methods. Given the complexity of the data handled by this class (including contract results, NFT transfers, and airdrops), clear documentation is vital for maintainability and contributor readability.

The following methods/components require comprehensive Google-style documentation:

1. Dataclass Parameters (__init__): The implicitly generated constructor needs documentation for all fields (e.g., transaction_hash, token_transfers, prng_bytes).
2. __repr__ method: Lacks a docstring explaining that it returns a human-readable string representation of the record.
3. _from_proto method: Needs expansion to clearly detail the complex data aggregation and mapping logic it performs (token transfers, NFT transfers, airdrop records).

💡 Solution

Implement comprehensive, Google-style docstrings throughout the specified file.

Proposed Solution

💡 Proposed Solution

The solution requires implementing or expanding documentation for the TransactionRecord class and its methods in src/hiero_sdk_python/transaction/transaction_record.py.

Step-by-Step Implementation:

1. Document Dataclass Fields: Add descriptive documentation for all fields defined in the TransactionRecord class.
2. Document __repr__ Method: Add a Google-style docstring explaining that it generates a human-readable string representation of the transaction data.
3. Expand _from_proto: Expand the existing docstring to full Google-style, detailing all inputs, the return value, and clarifying the method's role in aggregating all nested transfer data from the raw Protobuf.
4. Reference for Style: Follow the style conventions used in other SDK files.

📋 Requirements to Pass

• The __init__ parameters (dataclass fields), __repr__, and _from_proto methods must receive descriptive, Google-style docstrings.
• Update the CHANGELOG.md under ## [Unreleased] -> ### Added.
• All commits must be signed (-S and -s).

Implementation

Implementation

The contributor must perform the following technical steps in the file src/hiero_sdk_python/transaction/transaction_record.py:

1. Document Dataclass Fields: Add descriptive documentation for all fields defined in the TransactionRecord class (e.g., transaction_hash, token_transfers, prng_number).
2. Document __repr__: Implement a docstring for the __repr__ method, explaining that it generates a comprehensive, human-readable string representation of the record.
3. Expand _from_proto: Expand the existing docstring to full Google-style, detailing that the method aggregates complex data (token transfers, NFT transfers, airdrop records) from the raw Protobuf message.
4. Compliance: Ensure the final commit is DCO (-s) and GPG (-S) signed.
5. Changelog: Update the CHANGELOG.md under ## [Unreleased] -> ### Added.
