# nopcommerce_mobile

This is the official Flutter mobile app by nopCommerce.

## Setup project

Download project

```bash
git clone https://github.com/nopSolutions/nopCommerce-mobile-app.git
```

Get flutter dependencies

```bash
flutter pub get
```

Run the app

```bash
flutter run
```

## Web API client generation

Istall the [OpenAPI Generator](https://openapi-generator.tech/) (Requires [Node.js](https://nodejs.org/en/download/))

To update the version of OpenAPI Generator, use the following command and select the latest stable version from the list provided.

```bash
openapi-generator-cli version-manager list
```

Create a file *openapitools.json*.
Use the [dart-dio](https://openapi-generator.tech/docs/generators/dart-dio) generator.

```json
{
  "$schema": "node_modules/@openapitools/openapi-generator-cli/config.schema.json",
  "spaces": 2,
  "generator-cli": {
    "version": "6.4.0",
    "generators": {
        "frontend": {
            "input-spec": "swagger.json",
            "generator-name": "dart-dio",
            "output": "frontend_api",
            "additionalProperties": {
                "pubName": "frontend_api"
            }
        }
    }
  }
}
```

It is necessary that the OpenAPI schema *swagger.json* be in the directory with the generator installed.

1. Call the following command to generate the client:

    ```bash
    openapi-generator-cli generate
    ```

1. The standard openapi-generator will only generate base code that uses libraries that rely on Dart's own code generation. Therefore, after the completion of the base generation, it is necessary to start the Dart generator:

    ```bash
    cd frontend_api
    flutter pub get  
    flutter pub run build_runner build -d
    ```

    As a result, we get a ready-made package, which will be located where you specified in  the configuration file or console command. It remains to include it in *pubspec.yaml*:

    ```yaml
    frontend_api: # <- nopCommerce generated api library
        path: lib/frontend_api
    ```

First, install the latest version of the dart-dio generator as described in the documentation. Currently, it's 7.14.0.

After running the `openapi-generator-cli generate` command, you'll receive a pubspec.yaml file that differs from the one supplied with the mobile app. To use the correct pub package versions, you need to replace the generated pubspec.yaml file with the file from the mobile app's frontend_api folder before running the following commands:

flutter pub get
dart run build_runner build -d

After this operation, should we delete the lib/frontend_api folder and move the frontend_api folder in the main directory to the lib/frontend_api location?

openapi-generator-cli version : 7.14.0
openapi-generator-cli generate
copied file from lib/frontend_api/pubspec.yaml to frontend_api/pubspec.yaml
cd frontend_api
frontend_api % flutter pub get  
frontend_api % dart run build_runner build -d

Failed.

Yes, you can completely replace the old lib/frontend_api folder with the newly generated one.

I'm also encountering this error:

Error:
  The method 'getInvocation' isn't defined for the type 'DartObjectImpl'.
   - 'DartObjectImpl' is from 'package:analyzer/src/dart/constant/value.dart'

Workaround:
1. First, run `dart pub downgrade analyzer`

It should look like the example below. Main problem is analyzer in version 8.4. you must downgrade to 8.2.

~\openapi-generator-cli\frontend_api>dart pub downgrade analyzer

< analyzer 8.2.0 (was 8.4.1)

2. Then, `dart run build_runner build -d`
