obj_edit_gen

Automatically generate code for converting to widget by annotating Dart classes

Setup

To configure your project for the latest released version of, obj_edit_gen see the example.

Example

Given a library test.dart with an Test class annotated with @ObjEdit():

import 'package:obj_edit_annotation/obj_edit_annotation.dart';

import 'obj_option.dart';
//flutter pub run build_runner build --delete-conflicting-outputs

@ObjEdit(head: "import 'obj_option.dart';")
class Test {
  @ObjEditTextSetting(
      sectionName: "section1",
      title: "Name",
      hint: "name1",
      icon: "Icons.person")
  String name;
  @ObjEditOptionSetting(
      sectionName: "section1",
      title: "Option",
      options: '<String>["option1","option2","option3"]')
  String option;

  @ObjEditOptionSetting(
      sectionName: "section1",
      title: "ObjOption",
      options:
          '<ObjOption>[new ObjOption("objOption1"),new ObjOption("objOption2"),new ObjOption("objOption3")]')
  ObjOption objOption;

  @ObjEditTextSetting(sectionName: "section2", title: "Name", hint: "name2")
  String name2;
  @ObjEditOptionSetting(
      sectionName: "section2",
      title: "Option",
      options: '<String>["option1","option2","option3"]')
  String option2;

  Test(this.name, this.option, this.objOption, this.name2, this.option2);
}

Building creates the corresponding part test.e.dart:

      ]),
    ]);
  }
}

Running the code generator

Once you have added the annotations to your code you then need to run the code generator to generate the missing .e.dart generated dart files.

run flutter pub run build_runner build in your package directory.

Annotation values

• class annotation: @ObjEdit.
• text|int|double field annotation: @ObjEditTextSetting
• option field annotation: @ObjEditOptionSetting
• bool field annotation: @ObjEditBoolSetting
• date field
