类函数式组件定义变量与传递给组件的变量不一致

[vfiee]

问题描述
类函数组件中定义变量，传递给组件，控制台报错变量not defined(编译出来的变量和传递的变量名不一致).

复现步骤

renderBaseItem(curr) {
        let { type = 'text' } = curr;
        let { formData = {} } = this.state;
        let readyRender = this.isReadyRender(curr);
        if (!readyRender) return;
        if (type === 'upload') {
            let uploadData = curr.value || [{ title: '图片' }];
            return <ImageList
                data={uploadData}
                onUpload={this.onUpload.bind(this)}
                onDelete={this.onDelete.bind(this)}
            />
        }
    }

期望行为
变量名一致，传递过去正常

补充信息
应该是类函数组件编译时，变量没有添加_$前缀
