lessql 0.0.1-alpha

A flutter plugin for sqlite.

LesSQL

LesSQL is a flutter plugin for sqlite.

Getting started

1.Import LesSQL

import 'package:lessql/lessql.dart';

2.Init databse

Define DB

class FooDB extends LesDB{

  @override
  String getName() {
    return 'foo_db';
  }

  @override
  int getVersion() {
    return 1;
  }

}

Define table

class FooTable1 extends LesTable{

  @override
  List<String> getColumnNames() {
    return ['c1','c2','c3','c4'];
  }

  @override
  List<String> getColumnTypes() {
    return [Contract.TYPE_NUMBER,Contract.TYPE_NUMBER,Contract.TYPE_NUMBER,Contract.TYPE_NUMBER,];
  }

  @override
  String getTableName() {
    return 'table1';
  }
  @override
  List<int> getPrimaryColumnIndexes() {
    return [1];
  }

  @override
  String getAutoIncrementID(){
    return "id";
  }
}

Init database

LesSQL.initLesDB(new FooDB(), [new FooTable1(),new FooTable2()]);

Insert

LesTable and LesEntity must correspond one-to-one

class FooEntity1 extends LesEntity{

  String c1;
  int c2;
  int c3;
  int c4;

  FooEntity1(this.c1,this.c2,this.c3,this.c4);

  @override
  List getValues() {
    return [c1,c2,c3,c4];
  }
}

Random random = new Random();
FooEntity1 entity1 = new FooEntity1(random.nextInt(10000).toString(),
                     random.nextInt(10000), 
                     random.nextInt(10000), 
                     random.nextInt(10000));
LesSQL.insert(new FooTable1(), entity1.getValues()).then(_updateDes);
