Balance Sheet API - Dart/Flutter Client

Balance Sheet is a stock balance sheet API that returns the statement of financial position for a US public company by ticker - assets, liabilities and shareholders' equity - straight from SEC filings: current assets, cash, receivables, current liabilities, equity and more. Paid plans add total assets and liabilities, long-term debt, and liquidity and leverage ratios like current ratio, quick ratio and debt-to-equity.

This is the Dart/Flutter client for the Balance Sheet API.

Installation

Add this to your pubspec.yaml:
