Question

在flutter中使用Hasura，出现如下错误，Graphql版本^3.0.0

{
    "resource": "/D:/example_hasura1/lib/county.dart",
    "owner": "dart",
    "code": "argument_type_not_assignable",
    "severity": 8,
    "message": "The argument type 'Widget Function(QueryResult, {refetch: void Function()})' can't be assigned to the parameter type 'Widget Function(QueryResult, {fetchMore: dynamic Function(FetchMoreOpti[![enter image description here][1]][1]ons), refetch: Future<QueryResult> Function()})'.",
    "source": "dart",
    "startLineNumber": 24,
    "startColumn": 9,
    "endLineNumber": 24,
    "endColumn": 347,
    "tags": []
}

Answer 1

而不是：建造者：（查询结果结果，{VoidCallback refetch}）{ ... }

添加第三个参数，如下所示： builder: (QueryResult result, {VoidCallback refetch, FetchMore fetchMore}) { ... }

而且我可以看到您没有检查错误。但是如果你这样做了，那么确保将它从 .error 更改为 .hasException
