There is a lot of screaming in the terminal, but no user-visible error.

My json which is asserted valid by jsonlint.com:

[{"mailbox":"ct87ugz5","id":"5cd7baf5cfcdca06a3f07759","from":"hohg8z+dxzd795mt5gns","to":["\"[email protected]\" \[email protected]\u003e"],"subject":"Alstroemeria Record","date":"2019-05-12T14:19:33+08:00","size":1527,"seen":false}]

Error:

TypeError: Instance of 'JSArray': type 'JSArray' is not a subtype of type 'Map<String, dynamic>'

When I paste the code to Android (Android Studio , Visual code ) it throws the following error: Missing Parameter type for ('v') The problem is here : json['data'].forEach((v) and also here data['data'] = this.data.map((v) => v.toJson()).toList();

部分格式的json数据无法转换.比如 : Partial json data cannot be converted. For example:

http://tingapi.ting.baidu.com/v1/restserver/ting?method=baidu.ting.billboard.billList&type=2&size=10&offset=0

I've been copy pasting code on and off all day, and having a "Copy" button that put the contents of the code box into the clipboard would be great. Loving the tool.

Something like this.

When json has a name with underline, it will convert to hump name. Like

{
"product_id": 1
}

will generate

class Product {
  int productId;

product_id -> productId. I think it's correspond to dart code style.

But how can I keep the name untouched if I want.

You can make this into a package, and when you add your package to the flutter project, you create a json file that you want to generate the dart class, and then type the generate command at the terminal to generate the corresponding dart class file

😂I do not know if there is a package with similar functions, I am looking forward to it!!

I used the site to create my model after giving it a json file, floats in my data were converted to integers. Took me some time do understand what happened. Kindly add a note for that on the site or set double if json has double. Thank you.

Here is my code

In line 8, I am getting the error " Missing Parameter type 'v' "

The class PersonInfoList is missing but used in generated code, thanks if you can fix this.

When i copy model from your website it will not modify all data of json there are some parameters and class which can not be generated please check and support.
