Custom scalar types should be listed in typesUsed

[sav007]

Android GraphQL requires custom scalar types to be listed in typesUsed array in IR.json file.
Custom scalar type should be defined in the same way as enum types. This definitions will be later used by android code generator and response adapters

For example:

"typesUsed": [
    {
      "kind": "???",
      "name": "Date",
      "description": "DateTime value"
    },
    {
      "kind": "EnumType",
      "name": "Episode",
      "description": "The episodes in the Star Wars trilogy",
      "values": [
        {
          "name": "NEWHOPE",
          "description": "Star Wars Episode IV: A New Hope, released in 1977."
        },
        {
          "name": "EMPIRE",
          "description": "Star Wars Episode V: The Empire Strikes Back, released in 1980."
        },
        {
          "name": "JEDI",
          "description": "Star Wars Episode VI: Return of the Jedi, released in 1983."
        }
      ]
    }

@martijnwalraven just checked and not sure that the fix works:

So I have next custom scalar type in my schema:

{
          "kind": "SCALAR",
          "name": "DateTime",
          "description": null,
          "fields": null,
          "inputFields": null,
          "interfaces": null,
          "enumValues": null,
          "possibleTypes": null
        }

Product type:

"kind": "OBJECT",
          "name": "Product",
          "description": null,
          "fields": [
            ...
            {
              "name": "createdAt",
              "description": null,
              "args": [],
              "type": {
                "kind": "NON_NULL",
                "name": null,
                "ofType": {
                  "kind": "SCALAR",
                  "name": "DateTime",
                  "ofType": null
                }
              },
              "isDeprecated": false,
              "deprecationReason": null
            },

Query:

query ShopWithDate {
  shop {
    products(first:50) {
      edges {
        node {
          title
          createdAt
        }
      }
    }
  }
}

Generated IR.json

{
	"operations": [
		{
			"operationName": "ShopWithDate",
			"operationType": "query",
			"variables": [],
			"source": "query ShopWithDate {\n  shop {\n    products(first: 50) {\n      edges {\n        node {\n          title\n          createdAt\n        }\n      }\n    }\n  }\n}",
			"fields": [
				{
					"responseName": "shop",
					"fieldName": "shop",
					"type": "Shop!",
					"fields": [
						{
							"responseName": "products",
							"fieldName": "products",
							"type": "ProductConnection!",
							"fields": [
								{
									"responseName": "edges",
									"fieldName": "edges",
									"type": "[ProductEdge!]!",
									"fields": [
										{
											"responseName": "node",
											"fieldName": "node",
											"type": "Product!",
											"fields": [
												{
													"responseName": "title",
													"fieldName": "title",
													"type": "String!"
												},
												{
													"responseName": "createdAt",
													"fieldName": "createdAt",
													"type": "DateTime!"
												}
											],
											"fragmentSpreads": [],
											"inlineFragments": []
										}
									],
									"fragmentSpreads": [],
									"inlineFragments": []
								}
							],
							"fragmentSpreads": [],
							"inlineFragments": []
						}
					],
					"fragmentSpreads": [],
					"inlineFragments": []
				}
			],
			"fragmentsReferenced": []
		}
	],
	"fragments": [],
	"typesUsed": []
}

"typesUsed": [] - is empty

Are you sure you are running the latest version of apollo-codegen?

will check again, with npm I'm not sure about anything :)

[sav007]
