This package is a simplified version of Azure Identity for Dart.
Azure Identity provides token authentication mechanisms via Microsoft Entra ID identities. Since different authentication mechanisms are supported, it can be used to authenticate locally with a service deployed on Azure but can also be used to authenticate a Dart service with another service deployed on Azure.
Microsoft offers implementations for different architectures, but no implementation exists for Dart. This package aims to be a starting point for building a similar, feature equivalent solution.
A first version of this package used a work-around by using a NodeJS shim that called DefaultAzureCredential(). The NodeJS shim was cross-compiled to a binary and executed via shell environment. While this had the downside of not being publishable on pub.dev, it provided a very versatile initial solution. This version of the package is still available in the bridged-implementation branch.
The current code is pure native Dart code and supports the following credentials:
- Managed Identity 2017 API version
- Managed Identity 2019 API version
- Azure CLI credential
- Proxied Azure CLI credential (custom addition to enable locally running Docker containers to use Azure Identity)
- Chained credential
- Default credential (a chained credential of Managed Identity 2017, Managed Identity 2019, Azure CLI)
