import argparse
import os.path
from zipfile import ZipFile
parser = argparse.ArgumentParser()
parser.add_argument("app", help="Path to IPA file")
args = parser.parse_args()
ipalocation = args.app

if not os.path.isfile(ipalocation):
    raise Exception("file missing")

ipazip = ZipFile(ipalocation)
file_list = ipazip.namelist()
flutter_list = [
    f
    for f in file_list
    if 'flutter' in f.lower()
]

if len(flutter_list) > 10:
    print("This is flutter app")
else:
    print("This is not a flutter app")
