Flutter ORM Mate - flutter_orm_m8

Flutter package for ORM annotations.

Introduction

The package adds definitions for a set of types that could be combined to expand ORM capabilities in the annotated code. The current version, defines three annotation types:

• ColumnMetadata
• DataTable
• DataColumn

In order to ease the code emitting three abstract classes are defined:

• DbEntity
• DbAccountEntity
• DbAccountRelatedEntity

ColumnMetadata

The ColumnMetadata describes the basic options for a column definition:

• Ignore
• PrimaryKey
• Unique
• NotNull
• AutoIncrement
• Indexed

The options may be combined in various ways using | operator

@DataColumn("id", ColumnMetadata.PrimaryKey | ColumnMetadata.Unique | ColumnMetadata.AutoIncrement)

DataTable

DataTable describes the required name for the table

@DataTable("a01_tests")
class A01Test implements DbAccountRelatedEntity {

DataColumn

DataColumn describes the required name for the column in conjunction with a bit mask for required ColumnMetadata's

  @DataColumn("id", ColumnMetadata.PrimaryKey | ColumnMetadata.Unique | ColumnMetadata.AutoIncrement)
  int _id;

Usage

@DataTable("a01_tests")
class A01Test implements DbAccountRelatedEntity {
  @DataColumn("id", ColumnMetadata.PrimaryKey | ColumnMetadata.Unique | ColumnMetadata.AutoIncrement)
  int _id;

  @DataColumn("account_id")
  int _accountId;

  @DataColumn("record_date")
  int _recordDate;

  @DataColumn("is_deleted")
  int _isDeleted;
}
