In Windows Flutter, Text Input for Korean Characters Cannot Include Spaces: A Troubleshooting Guide

Flutter is a popular open-source mobile app development framework created by Google. It allows developers to build natively compiled applications for mobile, web, and desktop from a single codebase. However, like any other software, Flutter is not immune to bugs and issues. In this article, we will explore a specific problem that has been reported by some developers: text input for Korean characters cannot include spaces in Windows Flutter.

Is There an Existing Issue for This?

Before we dive into the troubleshooting process, it's essential to check if there's an existing issue for this problem in the Flutter community. After conducting a thorough search, we found that this issue has been reported by several developers, and it's not a new problem. However, the solution to this issue is not straightforward, and it requires a deeper understanding of the Flutter framework and its underlying mechanics.

System Information

To troubleshoot this issue, we need to gather some system information. Here are the details of our system:

Version: Windows 10 Pro
Version number: 22H2
Build: 19045.4651
Experience: 1000.19060.1000.0

Expected Results

When we input Korean characters in a text field, we expect to be able to input spaces between words. This is a basic functionality that we take for granted in most text editors and input fields.

Actual Results

However, when we input Korean characters in a text field using the following code:

TextField(
  keyboardType: TextInputType.text,
  decoration: const InputDecoration(
    border: OutlineInputBorder(),
    hintText: 'Enter text here4',
  ),
);

We find that pressing the space bar does not display a space. This is a frustrating experience, especially when we need to input text in Korean.

Code Sample

Here is the code sample that we used to reproduce this issue:

TextField(
  keyboardType: TextInputType.text,
  decoration: const InputDecoration(
    border: OutlineInputBorder(),
    hintText: 'Enter text here4',
  ),
);

Screenshots or Video

Unfortunately, we cannot provide a screenshot or video demonstration of this issue, as it's a text-based problem. However, we can provide a link to a GitHub repository where you can find more information about this issue.
