Undocumented GraphQL specification limitations and unsupported GraphQL types

[ryankauk]

Issues

• abstract class of interface type has no method build() but the implementations of them do

abstract class MyInterfaceBuilder {
  void replace(MyInterface other);
  void update(void Function(MyInterfaceBuilder) updates);
  MyInterfaceType get type;
  set type(MyInterfaceType type);
}

• Inline fragment Interface is building extension with static type "Character" referenced in example
  

  major/major_graphql_generator/lib/src/builders/executable/print_inline_fragments.dart

  Line 163 in 7b4eb63

  Character build() => null;

• This ends up getting generated for my interface type

@BuiltValue(instantiable: false)
abstract class MyInterfaceType  {
    if (selectionSet is Closure: (String) => String from Function 'selectionSetOf': static.(MyInterfaceTypeExtension)){
        return MyInterfaceTypeExtensionBuilder();
    }
}

when it should be:

@BuiltValue(instantiable: false)
abstract class MyInterfaceType  {
    if (selectionSet is MyInterfaceTypeExtension){
        return MyInterfaceTypeExtensionBuilder();
    }
}

Unsupported GraphQL Types

• Unions: Errors show up because the types don't implement the union name

Are unions able to be supported? I couldn't find an example or test case with it and have and issue with the property

Limitations on GraphQL Definitions

• No capitals are allowed on field

• Field name cannot be named the same thing as a root type

• filenames must be .graphql

• No documentation for options

  Overall I don't see these things as a big deal but I think they should be stated somewhere.
