![]() You can print or save the script directly from the JSON Preview dialog. ![]() ![]() To view the DDL generated by the currently selected settings, click the JSON Preview button on the wizard at anytime.You can also display or hide object owner names for those objects with owners. If you right-click anywhere on the object tree within the wizard, you can select or deselect all objects using the short-cut menu.Under the Collection tab you can select which collections from your model that you would like to be added to your JSON file. Below you can see the explanation of some specific objects. The Generation Options are on the tabs where you select the objects in the data model for which you would like to build the JSON file. See how you can load DDL Generation Wizard settings from a file created on a previous session. This option is not available during JSON file creation. Generate Objects with a Database Connection Base Directory: This control allows you to specify the directory that is to contain the generated script files.Objects are ordered in subdirectories for each selected object class. Generate Objects To Multiple Files: If selected, it writes a separate JSON file for each selected object.Database Creation Script File: This control allows you to provide the filename and path for the generated JSON file.Generate a Single, Ordered Script File: If selected, it writes a single JSON file with specification of all objects.Follow the pages of DDL Generation Wizard because they easily guide you through the rest of the process.On the Data Model Explorer, select a physical model and then choose Database > Generate Database.The DDL Generation Wizard lets you generate JSON code to build a MongoDB database. ![]() 2.1 Object Selection and Generation Options.1.2 Generate Objects with a Database Connection.The complete list of Dart and Flutter Code Generation, JSON Serialization and Annotation packages is provided below. Annotations can be useful for providing additional context to your code, and can also be used by tools such as IDEs to provide better code completion and error checking. In Flutter, annotations are typically used to provide additional information about the types of data that are used in your code, such as the types of objects that are returned by a function or the types of parameters that are accepted by a method. The Flutter framework provides built-in support for serializing and deserializing JSON data, making it easy to work with JSON in your Flutter applications.Īnnotations are a way of adding metadata or additional information to your code. In Flutter, JSON serialization is often used for working with data that comes from web services or other external sources. JSON serialization is the process of converting data from a structured format, such as a JSON object, into a format that can be easily stored or transmitted. Code generation can make it easier to write and maintain code, as it can automate repetitive tasks and reduce the amount of manual coding that is required. In Flutter, code generation is used for a variety of purposes, such as generating code for working with JSON data, generating code for working with databases, and generating code for working with web services. Top Flutter Code Generator and Serialization (JSON) packagesĬode generation is a technique for automatically generating code based on certain input data or rules.
