Schema class

A portable representation of a database schema.

Instances of this type contain the database-only details of a ManagedDataModel and are typically instantiated from ManagedDataModels. The purpose of this type is to have a portable, differentiable representation of an application's data model for use in external tooling.

Constructors

Schema(List<SchemaTable> tables)

Creates an instance of this type with a specific set of tables.

Schema.empty()

Creates an empty schema.

Schema.from(Schema? otherSchema)

Creates a deep copy of otherSchema.

Schema.fromDataModel(ManagedDataModel dataModel)

Creates an instance of this type from dataModel.

Schema.fromMap(Map<String, dynamic> map)

Creates a instance of this type from map.
