I want to convert nested json string into json how could i do this
{2022: {Apr: 100.0}} // this is my string
I/flutter ( 7168): Error FormatException: Unexpected character (at character 2)// here error comes out
I/flutter ( 7168): {2022: {Apr: 100.0}}
jsonDecoder("jsonstring here")// I used this code
First encode String then decode it
import 'dart:convert';
void main() {
String i = "{2022: {Apr: 100.0}}";
var i2 = json.decode(json.encode(i));
print(i2);
}
You can import the dart library 'dart:convert' and use its method json.decode(<your json string>) to convert a JSON string into a JSON.
Not exactly sure about the question, but to encode everything one has these options:
One needs to add the flag before executing build_runner.
https://docs.flutter.dev/data-and-backend/serialization/json#generating-code-for-nested-classes
@JsonSerializable(explicitToJson: true)
class User {}
Or update/create the build.yaml in your root.
