ozaner / json_bigint Goto Github PK

Hi,

While trying to use json_bigint for learning about writing Flutter and dart apps I discovered the package doesn't recognize exponential notation for integers.

Using the example code as illustration,

String json =
    '{"sometext": "hello world!", "bignumber": 100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000}';

correctly parses bignumber as a BigInt, but

String json = '{"sometext": "hello world!", "bignumber": 1e+140}';

incorrectly parses bignumber as a double (just as convert does).

In my current use case I am pulling the number from an external website so have no direct control over when it decides to hand me an integer in integer notation or in exponential notation.

(Also, as a side note, the example code is missing the '}' closing character on the json declaration such that running the example code results in a runtime parsing error.)
