Plist Parser for Flutter ?

A Flutter Plugin for Plist parser supporting XML and Binary formats.

It’s written xml and binary parser from scratch for Dart and this is not dependent other native libraries.

This was inspired by some libraries. please see below details.

Installation ?

dependencies:
  plist_parser: "^0.0.1"

Usage ?

import 'package:plist_parser/plist_parser.dart';
import 'dart:io';

const xml = '''
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>string_type</key>
  <string>hello plist</string>
  <key>int_type</key>
  <integer>12345</integer>
  <key>double_type</key>
  <real>12.345</real>
  <key>bool_type_true</key>
  <true/>
  <key>bool_type_false</key>
  <false/>
  <key>date_type</key>
  <date>2022-02-11T18:27:45Z</date>
  <key>data_type</key>
  <data>VGVzdCBWYWx1ZQ==</data>
  <key>dict_type</key>
  <dict>
    <key>key1</key>
    <string>value1</string>
    <key>key2</key>
    <integer>2</integer>
    <key>long_key_item_name_aaaaa_bbbbb_ccccc_ddddd_eeeee</key>
    <string>long_key_item_value_11111_22222_33333_44444_55555</string>
  </dict>
  <key>array_type</key>
  <array>
    <string>array item1</string>
    <string>array item2</string>
  </array>
  <key>array_type2</key>
  <array>
    <string>array2 item1</string>
    <dict>
      <key>nest_array</key>
      <array>
        <string>nest_array_item</string>
      </array>
      <key>nest_dict</key>
      <dict>
        <key>nest_dict_item</key>
        <integer>12345</integer>
      </dict>
    </dict>
  </array>
</dict>
</plist>
''';

void main() {
  // parse from xml string
  var result = PlistParser().parse(xml);
  print(result);
  print("int_type: ${result["int_type"]}");
  print("array_type[1]: ${result["array_type"][1]}\n");

  // parse from binary file sync
  filePath = "${Directory.current.path}/example/example_binary.plist";
  print("parseBinaryFileSync\n${PlistParser().parseBinaryFileSync(filePath)}\n"); 
}

The output are these:

// ※ Formatted for readability
{
    string_type: hello plist, 
    int_type: 12345, 
    double_type: 12.345, 
    bool_type_true: true, 
    bool_type_false: false, 
    date_type: 2022-02-11 18:27:45.000Z, 
    data_type: Test Value, 
    dict_type: {
        key1: value1, 
        key2: 2, 
        long_key_item_name_aaaaa_bbbbb_ccccc_ddddd_eeeee: long_key_item_value_11111_22222_33333_44444_55555
    }, 
    array_type: [
        array item1, 
        array item2
    ], 
    array_type2: [
        array2 item1, 
        {
            nest_array: [nest_array_item], 
            nest_dict: {
                nest_dict_item: 12345
            }
        }
    ]
}

int_type: 12345
array_type item2: array item2

parseBinaryFileSync
{array_type2: [array2 item1, {nest_dict: {nest_dict_item: 12345}, nest_array: [nest_array_item]}], date_type: 2022-02-11 18:27:45.000, double_type: 12.345, string_type: hello plist, bool_type_true: false, array_type: [array item1, array item2], bool_type_false: true, dict_type: {key1: value1, key2: 2, long_key_item_name_aaaaa_bbbbb_ccccc_ddddd_eeeee: long_key_item_value_11111_22222_33333_44444_55555}, data_type: Test Value, int_type: 12345}
