Extra Whitespace Appears When Text Ends With A Closing Parenthesis

by ADMIN 67 views

Introduction

When rendering text that ends with a closing parenthesis, such as (000), an unexpected extra whitespace appears on the right side. This issue can be observed in Flutter applications using the NumericText widget. In this article, we will delve into the steps to reproduce this behavior, the expected and actual outcomes, and the environment in which this issue occurs.

Steps to Reproduce

To reproduce this issue, follow these steps:

Step 1: Create a Flutter Application

Create a new Flutter project using your preferred IDE or code editor. For this example, we will use the NumericText widget in a simple Container widget.

Step 2: Use the NumericText Widget

Add the following code to your Flutter application:

Container(
  color: Colors.black,
  child: const NumericText(
    "(000)",
    duration: Duration(milliseconds: 250),
    style: TextStyle(fontWeight: FontWeight.w900, fontSize: 14, color: Colors.white),
  ),
);

This code creates a Container widget with a black background and a NumericText widget as its child. The NumericText widget displays the text (000) with a duration of 250 milliseconds and a style that includes a font weight of 900, a font size of 14, and a white color.

Step 3: Observe the Extra Whitespace

Run the application and observe that there is an unexpected extra whitespace on the right side of the text.

Step 4: Compare with Similar Strings

Compare this behavior with similar strings without the closing parenthesis, such as (000). You will notice that the extra whitespace is not present in these cases.

Expected Behavior

The text should render without any extra whitespace, regardless of whether it ends with a closing parenthesis. This is the expected behavior for the NumericText widget.

Actual Behavior

An extra whitespace is introduced on the right side when the text ends with a closing parenthesis, resulting in inconsistent rendering. This is the actual behavior observed in the NumericText widget.

Environment

The environment in which this issue occurs is:

  • NumericText version: 1.3.0
  • Flutter version: 3.29.1

Additional Context

This behavior appears to be related to how the widget calculates the text width when encountering a closing parenthesis. Any assistance or suggestions for resolving this issue would be greatly appreciated.

Possible Solutions

To resolve this issue, we can try the following possible solutions:

Solution 1: Trim the Text

One possible solution is to trim the text before rendering it. This can be done by using the trim() method in Dart.

Container(
  color: Colors.black,
  child: const NumericText(
    "(000)".trim(),
    duration: Duration(milliseconds: 250),
    style: TextStyle(fontWeight: FontWeight.w900, fontSize: 14, color: Colors.white),
  ),
);

Solution 2: Use a Custom Text Widget

Another possible solution is to create a custom text widget that handles the text width calculation differently. This can be done by creating a new widget that extends the Text widget and overrides the build() method.

class CustomText extends Text {
  @override
  Widget build(BuildContext context) {
    return super.build(context);
  }
}

Solution 3: Update the NumericText Widget

If the above solutions do not work, we can try updating the NumericText widget to fix the issue. This can be done by submitting a pull request to the NumericText repository or by creating a custom version of the widget.
