How to parse the json which contains array of array values using flutter. I know that this json format is not a valid but unfortunately I need to parse it.
{
ModuleEId: [
[
"Test Equipment - R&D",
"GPU_0001_180 KVA Dual AC 28.5V DC"
],
[
"Test Equipment - Electronics",
"GPU_0004_180 KVA Dual AC 28.5 V DC"
]
]
}
To parse a json you can use json.decode(jsonString) from package dart:convert. But first, you need to fix the format.
In this case, you could use for example replaceAll method to add the double quotes.
String jsonString = "/*loaded json*/";
jsonString = jsonString.replaceAll('ModuleEId', '"ModuleEId"');
And then
final parsed = json.decode(jsonString);
Full example: Dartpad
It is not a valid JSON, but it looks like valid YAML. You can take advantage of it.
Use yaml package: https://pub.dev/packages/yaml. Then convert it to JSON.
String input = """
{
ModuleEId:
[
[
"Test Equipment - R&D",
"GPU_0001_180 KVA Dual AC 28.5V DC"
],
[
"Test Equipment - Electronics",
"GPU_0004_180 KVA Dual AC 28.5 V DC"
]
]
}
""";
var yamlDoc = loadYaml(input);
final json = jsonEncode(yamlDoc);
print(((((jsonDecode(json)['ModuleEId'] as List)[0] as List)[0]) as String));
((((jsonDecode(string)['ModuleId'] as List)[0] as List)[0]) as String) == "Test Equipment - R&D"
