For example, you may need to persist data across app launches, or download data from the internet and save it for later offline use. To save files to disk, combine the path_provider plugin with the dart:io library. This recipe uses the following steps: Find the correct local path. The default is reading in text mode. In this mode, we get strings when reading from the file. On the other hand, binary mode returns bytes and this is the mode to be used when dealing with non-text files like images or executable files. CSV files with initial spaces. Some CSV files can have a space character after a delimiter. When we use the default csv.reader() function to read these CSV files, we will get spaces in the output as well. To remove these initial spaces, we need to pass an additional parameter called skipinitialspace. Let us look at an example: Reading files is one of the most essential tasks in programming.
