如何在flutter中显示json数据

Question

我有 json 数据，我想显示如下图所示。怎么办呢？？？

我尝试过一些软件包但不起作用。这是数据： {部署：{哈希：ac75b1d8664f2494f8aabcc218bb1ca6d819a44c223ddeb1f5367c3f4db51bf0，标头：{帐户：01f6EE89AC9acA3b01Ee2E33eFdbE899fF89B38D2DC7Fd2baC7B1f6 2FDD490f3F2，时间戳：2023-09-22T04：21：30.141Z，ttl：30m，gas_price：1，body_hash：be68953c273ff81ac1e62c975d27ecf8eafdda23203d70e116a6684216ebd385，依赖项：[]， chain_name：casper-测试}，付款：{ModuleBytes：{module_bytes：，args：[[金额，{bytes：0400e1f505，cl_type：U512}]]}}，会话：{转账：{args：[[金额，{bytes：0400f90295，cl_type： U512}]，[目标，{字节：0106ca7c39cd272dbf21a86eeb3b36b7c26e2e9b94af64292419f7862936bca2ca，cl_type：公钥}]，[id，{字节：010100000000000000，cl_type：{选项：U6 4}}]]}}，批准：[]}}
